-0.04x+1.4=0
Swap sides so that all variable terms are on the left hand side.
-0.04x=-1.4
Subtract 1.4 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-1.4}{-0.04}
Divide both sides by -0.04.
x=\frac{-140}{-4}
Expand \frac{-1.4}{-0.04} by multiplying both numerator and the denominator by 100.
x=35
Divide -140 by -4 to get 35.
