0.008x+1.9=y
Swap sides so that all variable terms are on the left hand side.
0.008x=y-1.9
Subtract 1.9 from both sides.
\frac{0.008x}{0.008}=\frac{y-1.9}{0.008}
Multiply both sides by 125.
x=\frac{y-1.9}{0.008}
Dividing by 0.008 undoes the multiplication by 0.008.
x=125y-237.5
Divide y-1.9 by 0.008 by multiplying y-1.9 by the reciprocal of 0.008.
