Question

Solve for X. -x/7 - 9 = -16
Why is the answer 49 and not -103?

Answer 1

why do u think that the answer should be -103??????

Answer 2

because if times -16 * 7 that would be -112 then + 9 = -103

Answer 3

\[\huge -\frac{ x }{ 7 } - 9 = -16\]
you add 9 to both sides first.
then multiply by -7 to both sides..
\[\huge -\frac{ x }{ 7 } = -7\]
\[\huge \cancel{-7} * \frac{ x }{ \cancel{-7} } = -7 * -7\]
\[\huge x= 49\]

Answer 4

is that a rule to add first then multiply?
