0.6x-22.9-1.5x=-18.4
Subtract 1.5x from both sides.
-0.9x-22.9=-18.4
Combine 0.6x and -1.5x to get -0.9x.
-0.9x=-18.4+22.9
Add 22.9 to both sides.
-0.9x=4.5
Add -18.4 and 22.9 to get 4.5.
x=\frac{4.5}{-0.9}
Divide both sides by -0.9.
x=\frac{45}{-9}
Expand \frac{4.5}{-0.9} by multiplying both numerator and the denominator by 10.
x=-5
Divide 45 by -9 to get -5.
