1000=130+5x+220+250+80+60+x+20
Add 50 and 80 to get 130.
1000=350+5x+250+80+60+x+20
Add 130 and 220 to get 350.
1000=600+5x+80+60+x+20
Add 350 and 250 to get 600.
1000=680+5x+60+x+20
Add 600 and 80 to get 680.
1000=740+5x+x+20
Add 680 and 60 to get 740.
1000=740+6x+20
Combine 5x and x to get 6x.
1000=760+6x
Add 740 and 20 to get 760.
760+6x=1000
Swap sides so that all variable terms are on the left hand side.
6x=1000-760
Subtract 760 from both sides.
6x=240
Subtract 760 from 1000 to get 240.
x=\frac{240}{6}
Divide both sides by 6.
x=40
Divide 240 by 6 to get 40.
