3(x + 2) = 15 - Vidyadip

Question

3(x + 2) = 15

✓

Answer

3 (x + 2) = 15
Dividing both sides by 3, we get
$\frac{3(\text{x}+2)}{3}=\frac{15}{3}$
(x + 2) = 5
Subtracting 2 from both sides, we get
x + 2 - 2 = 5 - 2
x = 3
Verification:
Substituting x = 3 in L.H.S., we get
L.H.S. = 3 (x + 2) = 3(3 + 2) = 3(5) = 15, and R.H.S. = 15
L.H.S. = R.H.S.
Hence, verified.
