x-4=z+10-30
Subtract 5 from 1 to get -4.
x-4=z-20
Subtract 30 from 10 to get -20.
x=z-20+4
Add 4 to both sides.
x=z-16
Add -20 and 4 to get -16.
x-4=z+10-30
Subtract 5 from 1 to get -4.
x-4=z-20
Subtract 30 from 10 to get -20.
z-20=x-4
Swap sides so that all variable terms are on the left hand side.
z=x-4+20
Add 20 to both sides.
z=x+16
Add -4 and 20 to get 16.
