2.75x+0.75y=z
Swap sides so that all variable terms are on the left hand side.
2.75x=z-0.75y
Subtract 0.75y from both sides.
2.75x=-\frac{3y}{4}+z
The equation is in standard form.
\frac{2.75x}{2.75}=\frac{-\frac{3y}{4}+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{-\frac{3y}{4}+z}{2.75}
Dividing by 2.75 undoes the multiplication by 2.75.
x=\frac{4z-3y}{11}
Divide z-\frac{3y}{4} by 2.75 by multiplying z-\frac{3y}{4} by the reciprocal of 2.75.
2.75x+0.75y=z
Swap sides so that all variable terms are on the left hand side.
0.75y=z-2.75x
Subtract 2.75x from both sides.
0.75y=-\frac{11x}{4}+z
The equation is in standard form.
\frac{0.75y}{0.75}=\frac{-\frac{11x}{4}+z}{0.75}
Divide both sides of the equation by 0.75, which is the same as multiplying both sides by the reciprocal of the fraction.
y=\frac{-\frac{11x}{4}+z}{0.75}
Dividing by 0.75 undoes the multiplication by 0.75.
y=\frac{4z-11x}{3}
Divide z-\frac{11x}{4} by 0.75 by multiplying z-\frac{11x}{4} by the reciprocal of 0.75.
