0.05x=2.2+0.3y
Add 0.3y to both sides.
0.05x=\frac{3y}{10}+2.2
The equation is in standard form.
\frac{0.05x}{0.05}=\frac{\frac{3y}{10}+2.2}{0.05}
Multiply both sides by 20.
x=\frac{\frac{3y}{10}+2.2}{0.05}
Dividing by 0.05 undoes the multiplication by 0.05.
x=6y+44
Divide 2.2+\frac{3y}{10} by 0.05 by multiplying 2.2+\frac{3y}{10} by the reciprocal of 0.05.
-0.3y=2.2-0.05x
Subtract 0.05x from both sides.
-0.3y=-\frac{x}{20}+2.2
The equation is in standard form.
\frac{-0.3y}{-0.3}=\frac{-\frac{x}{20}+2.2}{-0.3}
Divide both sides of the equation by -0.3, which is the same as multiplying both sides by the reciprocal of the fraction.
y=\frac{-\frac{x}{20}+2.2}{-0.3}
Dividing by -0.3 undoes the multiplication by -0.3.
y=\frac{x}{6}-\frac{22}{3}
Divide 2.2-\frac{x}{20} by -0.3 by multiplying 2.2-\frac{x}{20} by the reciprocal of -0.3.
