5x-9+2x=3x+23-4x
Solution:
5x-9+2x=3x+23-4X
(5x+2x)-9=(3x-4x)+23
7x-9=-x+23
7x+x=23+9
8x=32
x=32/8
x=4

5x-9%2B2x=3x%2B23-4x Start with the given equation.


7x-9=3x%2B23-4x Combine like terms on the left side.


7x-9=-x%2B23 Combine like terms on the right side.


7x=-x%2B23%2B9 Add 9 to both sides.


7x%2Bx=23%2B9 Add x to both sides.


8x=23%2B9 Combine like terms on the left side.


8x=32 Combine like terms on the right side.


x=%2832%29%2F%288%29 Divide both sides by 8 to isolate x.


x=4 Reduce.

Answer:

So the answer is x=4
