How many solutions does the following equation have?

[3x + 12]= 18

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

Respuesta :

Answer:

B. One solution

Step-by-step explanation:

subtract 12 from both sides

[tex]3x=18-12[/tex]

subtract 12 from 18

[tex]3x=6[/tex]

divide each term by 3

[tex]\frac{3x}{3} =\frac{6}{3}[/tex]

[tex]x=\frac{6}{3}[/tex]

divide 6 by 3

[tex]x=2[/tex]
