Answer:
m = 1/2
n = 1
Step-by-step explanation:
4m + 4n = 6 ... (1)
10m + 2n = 7 ...(2)
From (1),
4m + 4n = 6
2(2m + 2n ) = 6 Divide both sides by 2
2m + 2n = 3
2n = 3 - 2m ...(3)
Substitute (3) in (2)
Therefore,
10m + 3 - 2m = 7
10m - 2m = 7 - 3
8m = 4 Divide both sides by 8
m = 4/8 = 1/2
m = 1/2
Substitute m = 1/2 in (3)
2n = 3 - 2(1/2)
2n = 3 - 1
2n = 2 Divide both sides by 2
n = 1
