Question

Solve the following equation $: (7y + 8) + 7= 8$

✓

Answer

$(7y +8) +7= 8$
$\Rightarrow \frac{7 y+8}{7}=8$
$\Rightarrow \frac{7 y+8}{7} \times 7=8 \times 7 \ldots($ Multiplying by $7)$
$\Rightarrow 7 y+8=56$
$\Rightarrow 7 y+8-8-56-8 \ldots($ Subtracting $8$ from both sides $)$
$\Rightarrow 7 y=48$
$\Rightarrow \frac{7 y}{7}=\frac{48}{7} . .($ Dividing by $7)$
$\Rightarrow y=\frac{48}{7}=6 \frac{6}{7}$
