Answer 2

Answer:

u + v = 27-(1)

2/3v =19-3/4u :- 3/4u + 2/3v =19

a1=1          b1=1        c1=27

a2=3/4     b2=2/3   c2=19

[x = b1c2 - b2c1 / a1b2 - a2b1]

u= 1*19 - 2/3*27 / 1*2/3 - 3/4*1

u = 19-18/ 2/3-3/4

u = 1/8-9/12

u = 12/-1

u = -12 -(3)

substituting (3) in (1)

-12+ v= 27

v = 27+12

v = 39
