Answer:
Bruce is 10 years old.
Explanation:
m - Madge age.
b - Bruce age.
Madge is six years older than Bruce.
m=b+6 or m-6=b
In five years the sum of their ages will be 36.
m+5 - Madge age after 5 years.
b+5 - Bruce age after 5 years.
m+5+b+5=36
m=b+6
b+6+5+b+5=36
2b+16=36
2b=36-16
2b=20 /:2
b=10
m=b+6=10+6=16
