2.6x-6.6=0.4x
Combine 2x and 0.6x to get 2.6x.
2.6x-6.6-0.4x=0
Subtract 0.4x from both sides.
2.2x-6.6=0
Combine 2.6x and -0.4x to get 2.2x.
2.2x=6.6
Add 6.6 to both sides. Anything plus zero gives itself.
x=\frac{6.6}{2.2}
Divide both sides by 2.2.
x=\frac{66}{22}
Expand \frac{6.6}{2.2} by multiplying both numerator and the denominator by 10.
x=3
Divide 66 by 22 to get 3.
