7x-2=-5y
Subtract 5y from both sides. Anything subtracted from zero gives its negation.
7x=-5y+2
Add 2 to both sides.
7x=2-5y
The equation is in standard form.
\frac{7x}{7}=\frac{2-5y}{7}
Divide both sides by 7.
x=\frac{2-5y}{7}
Dividing by 7 undoes the multiplication by 7.
5y-2=-7x
Subtract 7x from both sides. Anything subtracted from zero gives its negation.
5y=-7x+2
Add 2 to both sides.
5y=2-7x
The equation is in standard form.
\frac{5y}{5}=\frac{2-7x}{5}
Divide both sides by 5.
y=\frac{2-7x}{5}
Dividing by 5 undoes the multiplication by 5.
