2+10x=7x+30-4
Subtract 19 from 21 to get 2.
2+10x=7x+26
Subtract 4 from 30 to get 26.
2+10x-7x=26
Subtract 7x from both sides.
2+3x=26
Combine 10x and -7x to get 3x.
3x=26-2
Subtract 2 from both sides.
3x=24
Subtract 2 from 26 to get 24.
x=\frac{24}{3}
Divide both sides by 3.
x=8
Divide 24 by 3 to get 8.
