Chapter 1 Test-8th grade Math

y - 33 = 147

• y = 114
• y = 177
• y = 180
• Answer not Given

-3a + 8 = 14

• a= -2
• a= -7.5
• a= 2
• a= 6

• x=10

• x=5

• x=40

• x=20

• x = 36

• x = 4

• x = 6

• x = 2/3

-2x + 14 + 8x = -10

• x = -2

• x = -4

• x = 4

• x = 2

 $6\left(2x\ -\ 3\right)\ -8\ =\ -2$  

• 2

• 3

• 4

• 1

What is the first step when solving for y?  7 + 4y = 39

• subtract 7 from both sides

• add 7 to both sides

• divide both sides by 4

• multiply both sides by 4

Describe the first step in solving the equation.

5(2x + 7) - 3x = 21

• Combine like terms

• Subtract 3x from both sides

• Distribute the 5 through (2x + 7)

• Multiply by 7

Solve:
3(x - 2) = 18

• 6.7
• 4
• 8
• -4

What is the first step in solving this equation 8x - 6 = 10

• Add 6

• Subtract 8

• Divide by 8

• Subtract 6
