6x=1.4-0.4y
Subtract 0.4y from both sides.
6x=\frac{7-2y}{5}
The equation is in standard form.
\frac{6x}{6}=\frac{7-2y}{5\times 6}
Divide both sides by 6.
x=\frac{7-2y}{5\times 6}
Dividing by 6 undoes the multiplication by 6.
x=-\frac{y}{15}+\frac{7}{30}
Divide \frac{7-2y}{5} by 6.
0.4y=1.4-6x
Subtract 6x from both sides.
\frac{0.4y}{0.4}=\frac{1.4-6x}{0.4}
Divide both sides of the equation by 0.4, which is the same as multiplying both sides by the reciprocal of the fraction.
y=\frac{1.4-6x}{0.4}
Dividing by 0.4 undoes the multiplication by 0.4.
y=\frac{7}{2}-15x
Divide 1.4-6x by 0.4 by multiplying 1.4-6x by the reciprocal of 0.4.
