3d+1+4=d-1
Multiply both sides of the equation by 4.
3d+5=d-1
Add 1 and 4 to get 5.
3d+5-d=-1
Subtract d from both sides.
2d+5=-1
Combine 3d and -d to get 2d.
2d=-1-5
Subtract 5 from both sides.
2d=-6
Subtract 5 from -1 to get -6.
d=\frac{-6}{2}
Divide both sides by 2.
d=-3
Divide -6 by 2 to get -3.
