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
