0.3x=3-0.1y
Subtract 0.1y from both sides.
0.3x=-\frac{y}{10}+3
The equation is in standard form.
\frac{0.3x}{0.3}=\frac{-\frac{y}{10}+3}{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.
x=\frac{-\frac{y}{10}+3}{0.3}
Dividing by 0.3 undoes the multiplication by 0.3.
x=-\frac{y}{3}+10
Divide 3-\frac{y}{10} by 0.3 by multiplying 3-\frac{y}{10} by the reciprocal of 0.3.
0.1y=3-0.3x
Subtract 0.3x from both sides.
0.1y=-\frac{3x}{10}+3
The equation is in standard form.
\frac{0.1y}{0.1}=\frac{-\frac{3x}{10}+3}{0.1}
Multiply both sides by 10.
y=\frac{-\frac{3x}{10}+3}{0.1}
Dividing by 0.1 undoes the multiplication by 0.1.
y=30-3x
Divide 3-\frac{3x}{10} by 0.1 by multiplying 3-\frac{3x}{10} by the reciprocal of 0.1.
