Question 3(Multiple Choice Worth 5 points)

When solving negative one over eight (x + 35) = −7, what is the correct sequence of operations?

A Multiply each side by negative one over eight , add 35 to each side
B Multiply each side by negative one over eight , subtract 35 from each side
C Multiply each side by −8, subtract 35 from each side
D Multiply each side by −8, add 35 to each side

Answer 1

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

Answer 2

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

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
