I believe for this type of question you can plug in any number but this is my answer
The answer of (y-1)= 9/2
Then, y=4.5+1
Thus, y= 5.5
Step 1: Flip the equation: 1/2 gw=d
Step 2: Divide both sides by w/2
You would get the answer like this: g=2d/w
180- 146
A=34 is the answer
4x+6=38
-6=-6
4x=32
4x/4=32/4
x=8
