If 2x/3 + 4 = 12, then x =

Question

A. x = 13.

B. x = 12.

C. x = -12.

D. x = -13.

Answer 1

correct answer is B. x=12

2x/3+ 4 = 2(12)/3 +4 =24/3 +4 =8+4 = 12

2x/3 +4 = 12

multiply by 3 to eliminate the fraction

2x +12 = 36

2x = 36-12 =24

2x =24 divide by 2

x = 12

Answer 2

If 2x/3 + 4 = 12, then x =

First you must get ride of the fraction by multiplying 3 on both sides 3(2x/3)+4=12(3)

Simply the equation by distributing the 3 and getting 2x+12=36

Subtract 12 from both sides and getting 2x=24

Divide both sides by 2 to get x by itself and you get x=12
