2.52x-5=y
Swap sides so that all variable terms are on the left hand side.
2.52x=y+5
Add 5 to both sides.
\frac{2.52x}{2.52}=\frac{y+5}{2.52}
Divide both sides of the equation by 2.52, which is the same as multiplying both sides by the reciprocal of the fraction.
x=\frac{y+5}{2.52}
Dividing by 2.52 undoes the multiplication by 2.52.
x=\frac{25y+125}{63}
Divide y+5 by 2.52 by multiplying y+5 by the reciprocal of 2.52.
