from both sides]

\Rightarrow\ \frac{5x}{2}=\frac{-7-8}{12}⇒

−7−8

\Rightarrow\ \frac{5x}{2}=\frac{-15}{12}⇒

−15

\Rightarrow\ 5x\times12=-15\times2⇒ 5x×12=−15×2

\Rightarrow60x=-30⇒60x=−30

\Rightarrow\ \frac{60x}{60}=\frac{-30}{60}⇒

60

60x

=

60

−30

[Dividing both sides by 60]

\Rightarrow\ x=\ \frac{-1}{2}⇒ x=
