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.
