Question

Solve the following equation:

4x - 3 = 12 + x

A x = 45

B x = 15

C x = 5

D x = 3

Answer 1

`4x - 3 = 12 + x \\ \\ ➪4x - x = 12 + 3 \\ \\ ➪3x = 15 \\ \\ ➪x = (15)/(3) = 5`

C] x = 5 Is ᴛʜᴇ ʀɪɢʜᴛ ᴀɴsᴡᴇʀ.

Answer 2

C x = 5

Explanation:

4x - 3 = 12 + x

Add 3 on both sides:
4x - 3 + 3 = 12 + 3 + x

4x = 15 + x

Subtract x from both sides:
4x - x = 15 + x - x

3x = 15

x = 15/3

or

x = 5
