Question

M *6+17=65
100-(3*n+5*n)=44

Answer 1

M *6+17=65
M*6=65-17
M*6=48
M=48:6
M=8

100-(3*n+5*n)=44
8*n=100-44
8*n=56
n=56:8
n=7

Answer 2

a) M x 6 + 17 = 65
M x 6 = 65 - 17
M x 6 = 48
M = 48 : 6
M = 8


b) 100 - ( 3 x N + 5 x N ) = 44
3 x N+ 5 x N= 100 - 44
3 x N+ 5 x N = 56
8 x N= 56
N= 56 : 8
N= 7


Success !!!
