Question

How many solutions does the following equation have?

[3x + 12]= 18

A. No solution
B. One solution
C. Two solutions
D. Infinitely many solutions​

Answer 1

B. One solution

Explanation:

subtract 12 from both sides

`3x=18-12`

subtract 12 from 18

`3x=6`

divide each term by 3

`(3x)/(3) =(6)/(3)`

`x=(6)/(3)`

divide 6 by 3

`x=2`
