What is the main focus of the transition from algebraic expressions to basic equation solving?

• Finding equivalent expressions

• Simplifying fractions

• Isolating the variable

• Rearranging terms

In solving equations, what is the primary goal?

• To factor the equation

• To simplify the expression

• To rearrange the terms

• To find the unknown value of the variable

What must be done to both sides of an equation when performing an operation?

• Multiply by different numbers

• Perform the same operation

• Add different values

• Subtract different values

Why is it important to undo operations in reverse order when solving equations?

• To make the equation more complex

• To avoid fractions

• To ensure the variable is isolated correctly

• To simplify the equation

What is the first step in solving the equation 3x + 5 = 17?

• Divide both sides by 3

• Add 5 to both sides

• Subtract 5 from both sides

• Multiply both sides by 3

What is the result of subtracting 5 from both sides of the equation 3x + 5 = 17?

• 3x = 22

• 3x = 12

• 3x = 17

• 3x = 5

After subtracting 5 from both sides, what is the next step in solving 3x + 5 = 17?

• Subtract 3 from both sides

• Divide both sides by 3

• Multiply both sides by 3

• Add 3 to both sides

What is the solution to the equation 3x + 5 = 17?

• x = 6

• x = 3

• x = 5

• x = 4

Why is it not strategic to divide by 3 first in the equation 3x + 5 = 17?

• It simplifies the equation

• It makes the equation more complex

• It creates a fraction equation

• It isolates the variable

What happens if you divide every term in 3x + 5 = 17 by 3?

• The equation becomes simpler

• The equation becomes a fraction equation

• The variable is isolated

• The equation is solved
