Question

In the algebraic equation $3(x+3)=12$, the value of the unknown is

• A. $-1$
• B. $0$
• C. $1$

Answer 1

The correct option is C $1$

Given algebraic equation : $3(x+3)=12$
Divide by $3$ on both the sides
$\frac{3(x+3)}{3}=\frac{12}{3}$
$\Rightarrow x+3=4$
Subtract $3$ from both the sides
$x+3-3=4-3$
$\Rightarrow x=1$
The value of the unknown $x$ is $1$ in the given algebraic equation.
