1.5(x+4)-3=4.5(x-2)
First, distribute 1.5 into x and 4, and 4.5 into x and -2, to get rid of the parentheses. Everything that we do to solve this equation is to isolate x to solve for its value.
1.5x+6-3=4.5x-9
Combine like terms on both sides (6-3).
1.5x+3=4.5x-9
Subtract 1.5x from both sides.
3=3x-9
Add 9 to both sides.
12=3x
Divide both sides by 3.
4=x
The answer is 4.
I hope this helps :)

Answer: 5
Step-by-step explanation:
Because the shape is a kite we can tell that WX and WZ are congruent.
So 4x-8 = 2x+2
Add 8 to both sides
4x = 2x+10
Subtract 2x
2x = 10
Divide by 2
x = 5
