Question

7-x/3=15

Answer 1

\[7 - \frac{ x }{ 3 } = 15\]

Is that what it looks like?

Answer 2

7 - x/3 = 15 (multiply everything by 3 to get rid of the fraction)
(3)7 - (3)x/3 = (3)15
21 - x = 45
21 - 45 = x
- 24 = x
check...
7 - (-24/3) = 15
7 + 24/3 = 15
7 + 8 =15
15 = 15 (correct)
ANSWER : x = - 24

Answer 3

any questions ?

Answer 4

OR in case it is

\[\frac{ 7 - x }{ 3 } = 15\]

multiply everything by 3 to get rid of the fraction

\[7 - x = 45\]

add x to both sides and subtract 45 from both sides

\[7 = 45 + x\]

\[x = 7 - 45\]
\[x = -38\]

So take your pick of my or @kelliegirl33 explanation depending on what your question looks like
