0+204x+3x-66=200x-35
Multiply 0 and 1 to get 0.
0+207x-66=200x-35
Combine 204x and 3x to get 207x.
-66+207x=200x-35
Subtract 66 from 0 to get -66.
-66+207x-200x=-35
Subtract 200x from both sides.
-66+7x=-35
Combine 207x and -200x to get 7x.
7x=-35+66
Add 66 to both sides.
7x=31
Add -35 and 66 to get 31.
x=\frac{31}{7}
Divide both sides by 7.
