1.31x+0.04-1.35x=-0.04
Subtract 1.35x from both sides.
-0.04x+0.04=-0.04
Combine 1.31x and -1.35x to get -0.04x.
-0.04x=-0.04-0.04
Subtract 0.04 from both sides.
-0.04x=-0.08
Subtract 0.04 from -0.04 to get -0.08.
x=\frac{-0.08}{-0.04}
Divide both sides by -0.04.
x=\frac{-8}{-4}
Expand \frac{-0.08}{-0.04} by multiplying both numerator and the denominator by 100.
x=2
Divide -8 by -4 to get 2.
