Answer 1

Answer:

b) m = 54, n = -78 c) p = 11/9, q = -7/9

Answer 2

Answer: m =54 and n= -78

Step-by-step explanation:

3m +2n = 6. ...(1)

m+n = -24. ...(2)

By multiplying (2) by 2, then we get

2m+2n= -48. ...(3)

Now subtracting (3) from (1)...

m = 54

Now putting m=54 in (2)....

54 + n = -24

n = -24 - 54

n = -78

Hence we get m = 54 and n = -78.

Hope it helps....
