Question

wat x+7>-15 i need to show how i got the answer plz help me out

Answer 1

\[x > -21\]
\[x \in \left( -21,\infty \right) \]

Answer 2

\[\frac{ 5 }{ 7b } - \frac{ 3 }{ 2b } = \frac{ -55 }{ 42 }\]
\[\frac{ 10b-21b }{ 14b^2 } = \frac{ -55 }{ 42 }\]
multiplying by 14 we get
\[10 - 21 = -55b/3\]
-11 = -55b/3
-33/-55 = b
b = 3/5
