7x-7-6y=5\left(x+y\right)
Use the distributive property to multiply 7 by x-1.
7x-7-6y=5x+5y
Use the distributive property to multiply 5 by x+y.
7x-7-6y-5x=5y
Subtract 5x from both sides.
2x-7-6y=5y
Combine 7x and -5x to get 2x.
2x-6y=5y+7
Add 7 to both sides.
2x=5y+7+6y
Add 6y to both sides.
2x=11y+7
Combine 5y and 6y to get 11y.
\frac{2x}{2}=\frac{11y+7}{2}
Divide both sides by 2.
x=\frac{11y+7}{2}
Dividing by 2 undoes the multiplication by 2.
7x-7-6y=5\left(x+y\right)
Use the distributive property to multiply 7 by x-1.
7x-7-6y=5x+5y
Use the distributive property to multiply 5 by x+y.
7x-7-6y-5y=5x
Subtract 5y from both sides.
7x-7-11y=5x
Combine -6y and -5y to get -11y.
-7-11y=5x-7x
Subtract 7x from both sides.
-7-11y=-2x
Combine 5x and -7x to get -2x.
-11y=-2x+7
Add 7 to both sides.
-11y=7-2x
The equation is in standard form.
\frac{-11y}{-11}=\frac{7-2x}{-11}
Divide both sides by -11.
y=\frac{7-2x}{-11}
Dividing by -11 undoes the multiplication by -11.
y=\frac{2x-7}{11}
Divide -2x+7 by -11.
