1\times 7+2-35+7y=9\times 7+1
Multiply both sides of the equation by 7.
7+2-35+7y=9\times 7+1
Multiply 1 and 7 to get 7.
9-35+7y=9\times 7+1
Add 7 and 2 to get 9.
-26+7y=9\times 7+1
Subtract 35 from 9 to get -26.
-26+7y=63+1
Multiply 9 and 7 to get 63.
-26+7y=64
Add 63 and 1 to get 64.
7y=64+26
Add 26 to both sides.
7y=90
Add 64 and 26 to get 90.
y=\frac{90}{7}
Divide both sides by 7.
