Question

Solve 3x - 1/2 = 8 1/2
a. x=2 2/3
b. x= 2 1/3
c. x= 8
d. x= 3

Answer 1

the correct answer is d. x=3

Explanation:

this is because you must isolate the variable by dividing each side by factors that don't contain the variable.

Answer 2

We will first add 1/2 to both sides to get 3x = 9
We then divide both sides by 3 to get
x =3 (D)
