Question

a)5x-2/3+6/5=7-x/3 x= b)2x-5(7+x)=9(2-x) c)3(x+2)-6x=8x-3(4+x)

Answer 1

a) 5x + 8/15 = 7 - x/3

75x + 8 = 105 - 5x

75x + 5x = 105 - 8

80x = 97

x = 97/80.

b) 2x - 35 - 5x = 18 - 9x

-3x - 35 = 18 - 9x

-3x + 9x = 18 + 35

6x = 53

x = 53/6.

c) 3x + 6 - 6x = 8x - 12 - 3x

-3x + 6 = 5x - 12

-3x - 5x = -12 - 6

-8x = -18

x = 9/4.
