Answer:
x=6
Step-by-step explanation:
(3/2)x - -4 =13
(3x/2)+4=13
Make 3x/2 the subject
3x/2=13-4
3x/2=9
Cross multiply
3x=9(2)
Divide both sides by 3
3x/3= 9(2)/3
x=3(2)
x=6
To check if correct, substitute x for 6 in the equation. And both sides of the equation must be equal
(3/2)x - -4 =13
(3/2)6 - -4 =13
18/2+4=13
9+4=13
13=13
