6+13x-13=5+10\left(y-1\right)
Use the distributive property to multiply 13 by x-1.
-7+13x=5+10\left(y-1\right)
Subtract 13 from 6 to get -7.
-7+13x=5+10y-10
Use the distributive property to multiply 10 by y-1.
-7+13x=-5+10y
Subtract 10 from 5 to get -5.
13x=-5+10y+7
Add 7 to both sides.
13x=2+10y
Add -5 and 7 to get 2.
13x=10y+2
The equation is in standard form.
\frac{13x}{13}=\frac{10y+2}{13}
Divide both sides by 13.
x=\frac{10y+2}{13}
Dividing by 13 undoes the multiplication by 13.
6+13x-13=5+10\left(y-1\right)
Use the distributive property to multiply 13 by x-1.
-7+13x=5+10\left(y-1\right)
Subtract 13 from 6 to get -7.
-7+13x=5+10y-10
Use the distributive property to multiply 10 by y-1.
-7+13x=-5+10y
Subtract 10 from 5 to get -5.
-5+10y=-7+13x
Swap sides so that all variable terms are on the left hand side.
10y=-7+13x+5
Add 5 to both sides.
10y=-2+13x
Add -7 and 5 to get -2.
10y=13x-2
The equation is in standard form.
\frac{10y}{10}=\frac{13x-2}{10}
Divide both sides by 10.
y=\frac{13x-2}{10}
Dividing by 10 undoes the multiplication by 10.
y=\frac{13x}{10}-\frac{1}{5}
Divide -2+13x by 10.
