2.75x=z
Swap sides so that all variable terms are on the left hand side.
\frac{2.75x}{2.75}=\frac{z}{2.75}
Divide both sides of the equation by 2.75, which is the same as multiplying both sides by the reciprocal of the fraction.
x=\frac{z}{2.75}
Dividing by 2.75 undoes the multiplication by 2.75.
x=\frac{4z}{11}
Divide z by 2.75 by multiplying z by the reciprocal of 2.75.
