Question

Solve the given equation: $3x+5=17$

• A. $x=3$
• B. $x=4$
• C. $x=5$
• D. This equation cannot be solved

Answer 1

The correct option is B $x=4$

$3x+5=17$
Subtracting 5 on both sides, we get,
$3x+5-5=17-5$
Hence, $3x=12$
Dividing by 3 on both sides, we get,
$x=\frac{12}{3}$
$\therefore x=4$
