Chapter 1 Review Algebra

Solve: 7x = 3x + 24

• 10

• 4

• 6

• 14

Solve: 10x + 9 = 4x - 9

• 3

• 0

• -18

• -3

In order to solve an equation, we must get variables on one side of an equation, and constants on the opposite side.

• False

• True

Solve: 2(4x-3) - 8 = 4 + 2x

• x=5/3

• x=3

• x=1

• x=2

Solve: x/8 = -2

• 16

• 6

• 10

• -16

What is the first step to solving this equation:

-11 - 3x = 44 - 2x

• Add 11 to both sides

• Get the variable on one side

• Add 3 to both sides

• Add 2 on both sides.

2x - 3 + 4x = 27

• 12
• 4
• 5
• 15

Solve for x:
4(1-x) + 3x = -2(x+1)

• x = -6
• x = 6
• x = 3

Jacob solved the following equation using the steps shown.

Step 1 5x + 9 = 2x - 3

Step 2 3x + 9 = -3

Step 3 3x = -12

Step 4 x = -4

What operation did he perform to get from Step 1 to Step 2?

• Subtracted 2x from both sides of the equation

• Subtracted 9 from both sides of the equation

• Multiplied both sides of the equation by 3

• Added -3 to both sides of the equation
