Jake, Tayo, and Blizzard have a combined age in dog years of 91. Tayo is 14 years younger than Jake. Blizzard is 6 years older than Jake. What is Jake's age, j, in dog years?

Use placeholders

j=jake's age

t=tayo's age

b=blizzard's age

j+t+b=91

t is 14 younger than j

t=-14+j

t=j-14

b is 6 more than j

b=6+j

j+t+b=91

t=j-14

b=6+j

subsitute j-14 for t in first equation and 6+j for b in first equation

j+j-14+6+j=91

3j-8=91

add 8 to bot sides

3j=99

divide by 3

j=33

sbsitute

b=6+j

b=6++33

b=39

t=j-14

t=33-14

t=19

j=33

t=19

b=39

jakes arge=33
