Question 233483
let G = number of dogs gray trained.
let J = number of dogs john trained.

G + J = 126


G = J + 32


Replace G with J + 32 in the first equation to get:


J + 32 + J = 126


Combine J to get:


2J + 32 = 126


Subtract 32 from both sides to get:


2J = 126 - 32 = 94


Divide both sides by 2 to get


J = 47


G = J + 32 = 47 + 32 = 79


J + G = 47 + 79 = 126


Your answer is:


Gray trained 79 and John trained 47
