If this is algebra then I can help
You would take the -9 and add 9 to it, that would cancel out the -9 but you would have to put it on the opposite side of the equation, that would show it as this: y=41+9, then you would simplify it to this: y=50
15x - 10 = -9x + 2
15x +9x -10 = -9x + 9x + 2
15 x + 9x - 10 + 10 = 2 + 10
15 x + 9 x = 2 + 10
24x = 12
24x/24 = 12/24
x = 1/2
hope this helps
