9x + 7 = 5x - 3
9x - 5x + 7 = 5x - 5x -3
4x + 7 = -3
4x + 7 - 7 = -3 - 7
4x = -10
x = -10/4 = -5/2

Move the x's one one side and the non-x's on the other:
9x + 7 + (-5x -7) = 5x - 3 + (-5x - 7)
4x = -10
x = -10/4
x = -2.5

9x + 7 = 5x - 3
9x - 5x = -3 - 7
4x = -10
x = -10/4
= -2.5 or -5/2

I believe the answer is -5/2 and 7 to both sides you get
9x=5x-10
subtract 5x from each side
4x=-10
and divide be 4
x=-10/4
and reduce
x=-5/2

9x-5x = -7 -3
4x = -10
x = -(10/4)
Reduced the answer is x = -5/2

9x + 7 = 5x - 3
4x = -10
x= - 5/2
hence x is - 2.5

first subtract 7 from both sides
9x=5x-10
subtract 5x from both sides
4x= -10
divide by 4
x= -5/2 or -2.5
