2x-1=3-2x-1\times 3x-1
Add 2 and 1 to get 3.
2x-1=3-2x-3x-1
Multiply 1 and 3 to get 3.
2x-1=3-5x-1
Combine -2x and -3x to get -5x.
2x-1=2-5x
Subtract 1 from 3 to get 2.
2x-1+5x=2
Add 5x to both sides.
7x-1=2
Combine 2x and 5x to get 7x.
7x=2+1
Add 1 to both sides.
7x=3
Add 2 and 1 to get 3.
x=\frac{3}{7}
Divide both sides by 7.
