Bisi and Daniels ages add up to29.seven years ago bisi was twice as old as Daniel. Find their present age.
B+d=29
B-7=2(d-7) or B-2d=-7
subtract equation 2 from eq 1
d+2d=29+7
3d=36
d=12
and from equation 1, B=29-12=17
B-7=2(d-7) or B-2d=-7
subtract equation 2 from eq 1
d+2d=29+7
3d=36
d=12
and from equation 1, B=29-12=17
