Question

If 2x + 3 = 5, then value of 3x + 2 is ______.

Answer 1

If 2x + 3 = 5, then value of 3x + 2 is 5.

Explanation:

Solve the given equation for x,

2x + 3 = 5

⇒ 2x = 5 – 3  ...[Transposing 3 to RHS]

⇒ `(2x)/2 = 2/2`  ...[Dividing both sides by 2]

⇒ x = 1

Put the value of x in (3x + 2), we get

3(1) + 2 = 3 + 2 = 5
