If Todd is 10 years older than Jamal, and the sum of their ages is 64. How old is Todd and Jamal?
j = Jamal's age
j + 10 = Todd's age {Todd is 10 years older than Jamal} j + j + 10 = 64 {the sum of their ages is 64} 2j + 10 = 64 {combined like terms} 2j = 54 {subtracted 10 from each side} j = 27 {divided each side by 2} j + 10 = 37 {substituted 27, in for j, into j + 10} Jamal is 27 Todd is 37 Ask Algebra House Comments are closed.
