Question

) (x - 5)/10 + (1 - 2x)/5 = (3-x)/4                                 (R: x = -21)

Answer 1

(x - 5) + (1 - 2x) = (3-x)                    mmc(5,4,10) = 20
   10           5            4

2(x - 5) + 2(1 - 2x) = 5(3-x)

2x - 10 + 2 - 4x = 15 - 5x

2x - 4x + 5x = 15 + 10 - 2

3x = 23

x = 23/3
