By B Horn
Review Course Notes
If your answer can be put in the form of a fraction, do so. If it can not, round your answer to the nearest thousandth.
Directions and/or Common Information:
Solve each equation using the shortcuts from section 3.5(5/6)x = 2
(2/6)x + 5 = (1/3)x
(7/3)x + (5/2) = 9/3
2[(4/3) - x] + 6 = 7/8
3[5x - (1/4)] = 9
(1/4)x - (7/2) = 2[(1/4)x + 3]
Directions and/or Common Information:
Solve each equation using the shortcuts in section 3.55.4x + 3 = 42
1.383x + 5.6 = 8.5
1.5 - 7.93x = 4.27(x - 5.93)
4.08(1.55 + 3.8x) - 2.8402 = 0.114x
0.129 - 5.38(0.772x + 3) = 0.6619
