2x-3\left(x-5x+10\right)=7x+30
Use the distributive property to multiply -5 by x-2.
2x-3\left(-4x+10\right)=7x+30
Combine x and -5x to get -4x.
2x+12x-30=7x+30
Use the distributive property to multiply -3 by -4x+10.
14x-30=7x+30
Combine 2x and 12x to get 14x.
14x-30-7x=30
Subtract 7x from both sides.
7x-30=30
Combine 14x and -7x to get 7x.
7x=30+30
Add 30 to both sides.
7x=60
Add 30 and 30 to get 60.
x=\frac{60}{7}
Divide both sides by 7.
