0.8-X-8.5*2=7 X-0.75X+1.6=12 5.6+X4X=17.28 40+X=468 X+0.2X=3

Answer 1

0.8-X-8.5*2=7

0.8-X=24

X=-23.2

X-0.75X+1.6=12

0.25X=10.4

X=41.6

5.6+4X=17.28

4X=11.68

X=2.92

40+X=468

X=428

X+0.2X=30

1.2X=30

X=25

6X- 3.2=5.8

6X=9

X=1.5

22+10X=77

10X=55

X=5.5

3.3X+6.7X-15=60

10X=75

X=7.5
