Question

there Are 3 brothers, Daryl, Malik, and Terrance who’s ages add up to 26 years. Daryl is 3 times as old as Mail, and Terrance is 5 years older than Daryl. Find the age of each brother.

Answer 1

Explanation:

Daryl=D

Malik=M

Terrance=T

D+M+T=26

D=3M

T=D+5

26-5=21

21=4M+D

4(3)+9=21

M=3

D=9

T=14

Answer 2

Daryl = 9, Malik = 3, Terrance = 14

Explanation:

We can use letters to represent each brother's name, so

D + M + T = 26

3M = D

D + 5 = T

then we can plug in the 3M in the third problem for D

3M + 5 = T

Then we can go back to the first problem and plug in 3M and (3M + 5)

3M + M + (3M + 5) = 26

4M + (3M + 5) = 26

7M = 21

M = 3

plug 3 in for M in the second equation:

3 x 3 = D

D=9

Then go back to the first equation:

9 + 3 + T = 26

12 + T = 26

T = 14

So T = 14

D = 9

and M = 3
