3+1.25a=14-1.5x
Swap sides so that all variable terms are on the left hand side.
1.25a=14-1.5x-3
Subtract 3 from both sides.
1.25a=11-1.5x
Subtract 3 from 14 to get 11.
1.25a=-\frac{3x}{2}+11
The equation is in standard form.
\frac{1.25a}{1.25}=\frac{-\frac{3x}{2}+11}{1.25}
Divide both sides of the equation by 1.25, which is the same as multiplying both sides by the reciprocal of the fraction.
a=\frac{-\frac{3x}{2}+11}{1.25}
Dividing by 1.25 undoes the multiplication by 1.25.
a=\frac{44-6x}{5}
Divide 11-\frac{3x}{2} by 1.25 by multiplying 11-\frac{3x}{2} by the reciprocal of 1.25.
-1.5x=3+1.25a-14
Subtract 14 from both sides.
-1.5x=-11+1.25a
Subtract 14 from 3 to get -11.
-1.5x=\frac{5a}{4}-11
The equation is in standard form.
\frac{-1.5x}{-1.5}=\frac{\frac{5a}{4}-11}{-1.5}
Divide both sides of the equation by -1.5, which is the same as multiplying both sides by the reciprocal of the fraction.
x=\frac{\frac{5a}{4}-11}{-1.5}
Dividing by -1.5 undoes the multiplication by -1.5.
x=-\frac{5a}{6}+\frac{22}{3}
Divide -11+\frac{5a}{4} by -1.5 by multiplying -11+\frac{5a}{4} by the reciprocal of -1.5.
