You can put this solution on YOUR website!
4x+5x-10=35
9x=35+10
9x=45
x=45/9
x=5 ans.
9x+6x-12x=-7x+2x-12+5x
9x+6x-12x+7x-2x-5x=-12
3x=-12
x=-12/3
x=-4 ans.

(1) 4x +5x -10 = 35
9x -10 =35,,,,,combining like terms
9x =45,,,,,,,,adding 10 to both sides
x=5,,,,,,,,,,,,,dividing by 9
.
(2) 9x+6x-12x = -7x +2x -12 +5x
3x = -12,,,,,,,,,combining like terms
x= -4,,,,,,,,dividing by 3
