Do u mean x + 3/5 = (x-2)/3 or (x+3)/5 = (x-2)/3?
If it's x + 3/5 = (x-2)/3:
5x + 3 = 5(x-2)/3 ---- Multiply by 5 throughout
15x + 9 = 5(x-2) ---- Multiply by 3 throughout
15x + 9 = 5x -10
15x - 5x = -10 - 9
10x = -19
x = -19/10
x = -1.9
If (x+3)/5 = (x-2)/3:
by cross-multiple:
3(x+3) = 5(x-2)
3x + 9 = 5x - 10
5x - 3x = 10 + 9
2x = 19
x = 19/2 = 9.5

x + 3/5 = x - 2/3
subtract x from each side
3/5 = -2/3
That doesn't work.
Maybe you mean,
(x+3)/5 = (x-2)/3
multiply both sides by 15
3(x+3) = 5(x-2)
3x+9 = 5x-10
19 = 2x
9.5 = x

(x + 5)/5 = (x - 2)/3
cross multiply
3(x + 3) = 5(x - 2)
3x + 9 = 5x - 10
-2x = -19
x = 9.5

Solve for X, if theres multiple choice substitute, or plug it into the graph of the calculator to find the points, therefore giving you what the x and y points would be.
