Question

For the equation $3x+5=17$, what will be the value of $x$?

• A. $x=44$
• B. $x=4$
• C. $x=\frac{4}{3}$
• D. $x=12$

Answer 1

The correct option is B

$x=4$

The given equation is $3x+5=17.$
Subtracting 5 from LHS and RHS, we will get,

$3x+5-5=17-5$
$\Rightarrow 3x=12$
On dividing LHS and RHS by 3, we will get, $x=4$.
Therefore, the value of x is 4.
