Two Step Equations

Solve for c: 4c - 8 = 0

• c = 1

• c = 2

• c = 3

• c = 4

Solve for a: 3a + 9 = 3

• a = 0

• a = 1

• a = -2

• a = 2

How do you check your solution in a two-step equation?

• Substitute the solution back into the original equation to see if both sides are equal.

• Multiply both sides of the equation by the same number.

• Add the same number to both sides of the equation.

• Graph the equation and see if the point lies on the line.

Solve for b: 5b = 25

• b = 10

• b = 2

• b = 5

• b = 15

Solve for a: 20 = 2 - a

• a = -16

• a = -18

• a = 18

• a = 22

Solve for y: -2y = 20

• y = 10

• y = -5

• y = -10

• y = 0

Solve for x: -4x + 1 = 21

• x = -5

• x = 5

• x = 0

• x = 10

What is the first step to solve the equation: 2x + 3 = 11?

• Add 3 to both sides.

• Subtract 3 from both sides.

• Multiply both sides by 2.

• Divide both sides by 2.

Identify the steps to solve for b in the equation: 5b - 6 = 24

• Add 6 to both sides and then divide both sides by 5.

• Subtract 6 from both sides and then multiply both sides by 5.

• Divide both sides by 5 and then add 6 to both sides.

• Multiply both sides by 5 and then subtract 6 from both sides.

What does it mean to perform the inverse operation?

• An inverse operation reverses the effect of the original operation (e.g., addition and subtraction are inverses).

• An inverse operation is a method to increase the value of a number.

• An inverse operation is a technique used to multiply two numbers together.

• An inverse operation is a way to simplify complex equations.
