Question

a=1/4(x-3),b=1/3(3-4x)find 1/2(a-b) plz fast

Answer 1

Answer:

(19x-21)/24

Step-by-step explanation:

a = 1/4(x-3) = x/4 - 3/4

b = 1/3(3-4x) = 1 - 4x/3

a - b = (x/4 - 3/4) - (1 - 4x/3)

= x/4 - 3/4 - 1 + 4x/3

= 19x/12 - 7/4

= (19x - 21)/12

Therefore, 1/2(a-b) = 1/2 [(19x - 21)/12]

= (19x - 21)/24

Hope it helps you.........
