Question

<br />$\frac{4x + 2}{x + 2} = \frac{4}{5}$<br />​

Answer 1

$\begin{gathered}\sf\dashrightarrow \frac{4x + 2}{x + 2} = \frac{4}{5} \\ \dashrightarrow \sf5(4x + 2) = 4(x + 2) \\ \sf\dashrightarrow 20x + 10 = 4 x + 8 \\ \sf\dashrightarrow 20x - 4x = 8 - 10 \\ \sf\dashrightarrow 16x = - 2 \\ \sf\dashrightarrow x = \frac{ - 2}{16} \\ \sf\dashrightarrow x = \frac{ - 1}{8} \end{gathered}$

Answer 2

→ 5(4x+2) = 4(x+2)

→20x+10= 4x+8

20x4x 8-10

→ 16x =-2

x= -1/8
