A is your answer hope this helps
<span>X/2 + 3/4 = 7/4
We want to isolate X by itself. Subtract 3/4 from both sides
X/2 = 4/4
X/2 = 1
Multiply both sides by 2 to cancel out the 1/2 on the same side of the X
X = 2</span>
Solve n by simplifying both sides of the equation, then isolating the variable.
n=7
