In part (b), use the methods of Section 4.4 to perform the subtraction. (a) x/4 - 1/9 x/2 x = (b)

Solution

solution

18. 13x=9x-7

or , 13x-9x= - 7

or, 4x=-7

or, x= -4/7

19. 1/4 = 2y - 3/5

or,    1/4+3/5 = 2y

or,    y =1/2*17/20

or,   y= 17/40

20. -3 = (-5/6)y

or,   y= 3*6/5

or,   y = 18/5

21.    (2/3)y+2=1/5+y

or,    y(1-2/3) = 2-1/5

or,     y = 9/5*3

or,   y=27/5
