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?

Respuesta :

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
