x\times 2=7-4y
Subtract 4y from both sides.
2x=7-4y
The equation is in standard form.
\frac{2x}{2}=\frac{7-4y}{2}
Divide both sides by 2.
x=\frac{7-4y}{2}
Dividing by 2 undoes the multiplication by 2.
x=\frac{7}{2}-2y
Divide 7-4y by 2.
4y=7-x\times 2
Subtract x\times 2 from both sides.
4y=7-2x
Multiply -1 and 2 to get -2.
\frac{4y}{4}=\frac{7-2x}{4}
Divide both sides by 4.
y=\frac{7-2x}{4}
Dividing by 4 undoes the multiplication by 4.
y=-\frac{x}{2}+\frac{7}{4}
Divide 7-2x by 4.
