Question
The solution of the equation $3x + 7 = -20$ is .
✓
Answer
Given, $3x + 7 = -20 $
$\Rightarrow 3x = -20 - 7$ [transposing $+7$ to $RHS] $
$\Rightarrow 3x = -27$
$\Rightarrow\frac{3\text{x}}{3}=\frac{-27}{3}$ [dividing both sides by $3] $
$\Rightarrow x = -9$
Hence, the solution of equation $3x + 7 = -20$ is $-9$
$\Rightarrow 3x = -20 - 7$ [transposing $+7$ to $RHS] $
$\Rightarrow 3x = -27$
$\Rightarrow\frac{3\text{x}}{3}=\frac{-27}{3}$ [dividing both sides by $3] $
$\Rightarrow x = -9$
Hence, the solution of equation $3x + 7 = -20$ is $-9$
