136-3x-1=6\times 34+2x-1
Multiply 4 and 34 to get 136.
135-3x=6\times 34+2x-1
Subtract 1 from 136 to get 135.
135-3x=204+2x-1
Multiply 6 and 34 to get 204.
135-3x=203+2x
Subtract 1 from 204 to get 203.
135-3x-2x=203
Subtract 2x from both sides.
135-5x=203
Combine -3x and -2x to get -5x.
-5x=203-135
Subtract 135 from both sides.
-5x=68
Subtract 135 from 203 to get 68.
x=\frac{68}{-5}
Divide both sides by -5.
x=-\frac{68}{5}
Fraction \frac{68}{-5} can be rewritten as -\frac{68}{5} by extracting the negative sign.
