Question

If x=m and y=n is the solution of the equations:8x-8y=16 and 7x+7y=28 then the values of m and n are , respectively a] 3 and 5 b]5 and 3 c] 3and 1 d] -1 and-3​

Answer 1

Answer:

b] 5 and 3

Step-by-step explanation:

it is given that x=m and y=n

if we suppose that m=5 and n=3

8x-8y=16, x=5 and y=3.

therefore, (8*5)-(8*3)=16

40-24=16

16=16

LHS=RHS

hence, the answer will be b] 5 and 3.
