Answer:

  • C Multiply each side by −8, subtract 35 from each side

Step-by-step explanation:

Solving the equation:

  • -1/8(x + 35) = -7

Multiply both sides by -8:

  • x + 35 = 56

Subtract 35 from both sides:

  • x = 56 - 35
  • x = 21

Correct answer choice is C

Given expression

  • -1/8(x+35)=-7

Option C is correct

As multiply each side by -8 will result removal of -1/8

  • x+35=56

Then subtracting 35 will give us x

  • x=56-35
  • x=21
