8th grade 4.4 practice

5x + 2(2x-4) = 55

What is your first step?

• subtract 4 from both sides

• multiply 2 times (2x-4)

• Subtract 5x from both sides

• subtract 2x from both sides

3x+2(x-6) = 33

What is the equation after you do the first step?

• 3x + 2x - 6 =33

• 3x + x - 12 = 33

• 3x + 2x - 12 = 33

• 3x + 2x + 12 = 33

4x + 3 (3x+7) = 86

What is step 1?

• Subtract 7 from both sides

• subtract 3 from both sides

• multiply 3 times (3x + 7)

• Subtract 21 from both sides

Solve:

7x+4(x-9) = 41

What is x?

Solve:

3x + 158 = 4(8x-4)

• x = 6

• x = 4

• x = 7

• x = 8
