Question

Solve: $(7y+4)/(y+2)=-4/3$

Answer 1

$(7y+4)/(y+2)=-4/3$
By the cross multiplication of terms,
$$\begin{gathered} \Rightarrow 3(7y+4)=-4(y+2) \\ \Rightarrow 21y+12=-4y–8 \\ \Rightarrow 21y+4y=-8–12 \\ \Rightarrow 25y=-20 \\ \Rightarrow y=-20/25 \\ \Rightarrow y=-4/5 \end{gathered}$$

Hence $y=\raisebox{1ex}{$-4$}\!\left/ \!\raisebox{-1ex}{$5$}\right.$ is correct .
