Answer:
1/4
Step-by-step explanation:
use PEMDAS first.
P=parenthesis
E=exponents
M= multiplication
D= division
A= addition
S=subtraction
you see a parenthesis so you have to distribute 4 to the variables in the parenthesis. 4 time x is 4x. 4 times 3/2 is 6. after distribution you get 4x+6=7. subtract 6 on both sides. 4x=1. divide 4 on both sides. x=1/4.
