1.1x-15=x-13
Combine 4x and -2.9x to get 1.1x.
1.1x-15-x=-13
Subtract x from both sides.
0.1x-15=-13
Combine 1.1x and -x to get 0.1x.
0.1x=-13+15
Add 15 to both sides.
0.1x=2
Add -13 and 15 to get 2.
x=\frac{2}{0.1}
Divide both sides by 0.1.
x=20
Expand \frac{2}{0.1} by multiplying both numerator and the denominator by 10. Anything divided by one gives itself.
