Question 412167
Let {{{b}}} = Bill's age now
Let {{{t}}} = Tom's age now
given:
(1) {{{b = t + 3}}}
(2) {{{b - 5 = 2*(t - 5)}}}
Substitute (1) into (2)
(2) {{{t + 3 - 5 = 2*(t - 5)}}}
(2) {{{t - 2 = 2t - 10}}}
(2) {{{t = 10 - 2}}}
(2) {{{t = 8}}}
and, since
(1) {{{b = t + 3}}}
(1) {{{b = 8 + 3}}}
(1) {{{b = 11}}}
Bill is 11 now and Tom is 8 now
