John is 13 years old
Mary is 14 years old
so
Jon's age=j
mary age=m
m+j=27
m+2 times j=40
m+2j=40
M+j=27
ssubtract j from both sides
m=27-j
subsitute 27-j for m
27-j+2j=40
27+j=40
subtract 27 fromboth sdies
j=13
subsitue
13+m=27
subtract 13
m=14
mary=14
john=13
Jon's age=j
mary age=m
m+j=27
m+2 times j=40
m+2j=40
M+j=27
ssubtract j from both sides
m=27-j
subsitute 27-j for m
27-j+2j=40
27+j=40
subtract 27 fromboth sdies
j=13
subsitue
13+m=27
subtract 13
m=14
mary=14
john=13
