Question

Solve for x: the quantity of x plus 4 over 3 = 2.

A. x = −2
B. x = 2
C. x = 2 over 3
D. x = negative 10 over 3

Answer 1

B. X=2
To remove the denominator (3), you multiply by 3 on both sides.
To remove +4, you -4 from both sides.
You have to do the equal steps on both sides, you can't just -4 on one side, as this will give you wrong answer.

Answer 2

(x+4)/3 = 2
x + 4 = 2*3
x + 4 = 6
x = 6 - 4
x = 2
