Two Step Equations

What is the solution to the equation 3(3x - 6) = 18?

• x = 2

• x = 3

• x = 4

• x = 5

What is the first step to solve the equation: -4x + 1 = 21?

• Subtract 1 from both sides to start isolating the variable.

• Add 1 to both sides to start isolating the variable.

• Multiply both sides by -4 to isolate x.

• Divide both sides by -4 to isolate x.

What is the importance of checking your solution in an equation?

• It helps to find the solution faster.

• It ensures that the value satisfies the original equation.

• It allows for more complex equations to be solved easily.

• It is not necessary if you feel confident about your answer.

How do you handle parentheses in equations like 3(3x - 6) = 18?

• Use the distributive property to eliminate parentheses by multiplying the term outside by each term inside.

• Add the terms inside the parentheses together before multiplying.

• Ignore the parentheses and solve the equation as is.

• Subtract the term outside the parentheses from the equation.

What is the solution to the equation 2x + 3x + 4 = 44?

• x = 6

• x = 7

• x = 8

• x = 9

What is the significance of the equal sign in an equation?

• It indicates that the expressions on both sides have the same value.

• It shows that the left side is greater than the right side.

• It separates the variable from the constant in the equation.

• It indicates that the equation is incomplete.

What does it mean to perform inverse operations?

• Inverse operations are operations that undo each other, such as addition and subtraction or multiplication and division.

• Inverse operations are operations that enhance each other, such as addition and multiplication.

• Inverse operations are operations that create new values without affecting the original value.

• Inverse operations are operations that only apply to negative numbers.

How do you solve the equation 3c + 5 = 23?

• Subtract 5 from both sides, then divide by 3 to find c.

• Add 5 to both sides, then multiply by 3 to find c.

• Divide both sides by 3, then subtract 5 to find c.

• Multiply both sides by 3, then add 5 to find c.

What is the distributive property?

• The distributive property states that a(b + c) = ab + ac, allowing you to multiply a single term by each term inside a parentheses.

• The distributive property states that a + (b + c) = (a + b) + c, allowing you to add numbers in any order.

• The distributive property states that a(b - c) = ab - ac, allowing you to multiply a single term by each term inside a parentheses.

• The distributive property states that a(b + c) = a + b + c, allowing you to add terms inside a parentheses.

How do you isolate a variable in an equation?

• By adding the same number to both sides of the equation until the variable is alone on one side.

• By performing inverse operations to both sides of the equation until the variable is alone on one side.

• By multiplying both sides of the equation by the variable's coefficient.

• By dividing both sides of the equation by the variable's exponent.
