Answer 1

g) 2.7 + 47x = 3/18

47x = 3/18 - 2.7

47x = 1/6 - 2.7

47x = -17.1

x = -17.1 / 47

x ≈ -0.3647

h) 5x + 4.2(33) = 111/30

5x + 138.6 = 111/30

5x = 111/30 - 138.6

5x = 111/30 - 4158/30

5x = -4047/30

x = -809.4/30

x ≈ -26.98

i) 0.58(3) - 3x = 3.25

1.74 - 3x = 3.25

-3x = 3.25 - 1.74

-3x = 1.51

x = 1.51 / -3

x ≈ -0.5033
