Hi there!
To solve this problem, we need to simplify.
5x + 32 = 4 - 2x
7x + 32 = 4
7x = -28
x = -4
Hope this helps!
It need to be more clear for me to read
The answer is (5+3)× 2-(6)=10
Use the midpoint formula

plug in points DF and ED to get (-3,0) and (0.5, 0)
The answer is 4 because nine less 8 no less that 3
