Question

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

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

Answer 1

If I multiply both sides, by \(−8\) I get this:
\[\left( { - 8} \right) \cdot \left( { - \frac{1}{8}} \right)\left( {x + 35} \right) = \left( { - 8} \right) \cdot \left( { - 7} \right)\]

Answer 2

please simplify

Answer 3

so would it be A Multiply each side by negative one over eight , add 35 to each side

Answer 4

please nothe that I have multiplied by \(-8\) not by \(-1/8\)

Answer 5

note*

Answer 6

so D

Answer 7

no i mean c

Answer 8

correct! since after that multiplication, I can write this:
\[x + 35 = 56\]
so, If I subtract \(35\) I get this:
\[x + 35 - 35 = 56 - 35\]
or:
\(x=21\)
