Question

Subtract of the 31 (1 - 4 m + 5 n)
from 41 ( 10 n-3 m +21) is​

Answer 1

31(1-4m+5n)

41(10n-3m+21)

31(-3m+5n)

41-21(10n-3m)

31(-3m+5n)

20(10n-3m)

31(-3m+5n)

20(3m+10n)

31= -3m+5n

20=3m+10n

__________

11= 0 + 5n .....(++= -)

11=5n

n=11\5

n=2.2

n=2.2 put the value equation one

31=-3m+5n

31=3m+5×2.2

31=3m+11

31-11=3m

20=3m

m=3/20

m=0.15

m=0.15,n=2.2
