-7\left(-4\right)=1-3x
Multiply both sides by -4, the reciprocal of -\frac{1}{4}.
28=1-3x
Multiply -7 and -4 to get 28.
1-3x=28
Swap sides so that all variable terms are on the left hand side.
-3x=28-1
Subtract 1 from both sides.
-3x=27
Subtract 1 from 28 to get 27.
x=\frac{27}{-3}
Divide both sides by -3.
x=-9
Divide 27 by -3 to get -9.
