3.4x+43=y
Swap sides so that all variable terms are on the left hand side.
3.4x=y-43
Subtract 43 from both sides.
\frac{3.4x}{3.4}=\frac{y-43}{3.4}
Divide both sides of the equation by 3.4, which is the same as multiplying both sides by the reciprocal of the fraction.
x=\frac{y-43}{3.4}
Dividing by 3.4 undoes the multiplication by 3.4.
x=\frac{5y-215}{17}
Divide y-43 by 3.4 by multiplying y-43 by the reciprocal of 3.4.
