Answer 1

A)

0.5x + 3 = 0.4x + 3.3

0.1x = 0.3

x=3

B)

3x + 0.8x = 2.4 + 0.9x

3x + (-0.1) = 2.4

2.9x = 2.4

x= 0.8

C)

0.2x - 0.03 = 0.17x + 0.21

0.2x - 0.17x = 0.21 + 0.03

0.03x = 0.24

x=8

D)

1.31x + 0.04 = 1.35x - 0.04

0.08 = 0.04x

2=x

E)

0.05x - 0.034 = 0.015x + 0.0001

0.035x = 0.0341

x=0.9

F)

2.25X + 1.97 = 3.75X - 0.004

1.966= 1.5X

1.3=X
