x-5x+10+6x=2x-\left(15-7x\right)+3x-5
Use the distributive property to multiply -5 by x-2.
-4x+10+6x=2x-\left(15-7x\right)+3x-5
Combine x and -5x to get -4x.
2x+10=2x-\left(15-7x\right)+3x-5
Combine -4x and 6x to get 2x.
2x+10=2x-15-\left(-7x\right)+3x-5
To find the opposite of 15-7x, find the opposite of each term.
2x+10=2x-15+7x+3x-5
The opposite of -7x is 7x.
2x+10=9x-15+3x-5
Combine 2x and 7x to get 9x.
2x+10=12x-15-5
Combine 9x and 3x to get 12x.
2x+10=12x-20
Subtract 5 from -15 to get -20.
2x+10-12x=-20
Subtract 12x from both sides.
-10x+10=-20
Combine 2x and -12x to get -10x.
-10x=-20-10
Subtract 10 from both sides.
-10x=-30
Subtract 10 from -20 to get -30.
x=\frac{-30}{-10}
Divide both sides by -10.
x=3
Divide -30 by -10 to get 3.
