7x+21-5\left(x-1\right)=x+28
Use the distributive property to multiply 7 by x+3.
7x+21-5x+5=x+28
Use the distributive property to multiply -5 by x-1.
2x+21+5=x+28
Combine 7x and -5x to get 2x.
2x+26=x+28
Add 21 and 5 to get 26.
2x+26-x=28
Subtract x from both sides.
x+26=28
Combine 2x and -x to get x.
x=28-26
Subtract 26 from both sides.
x=2
Subtract 26 from 28 to get 2.
