Answer:
Joe's age is 93 years
Aaron's age is 31 years
Christina's age is 25 years
Step-by-step explanation:
Let
x ---->Joe's age
y ----> Aaron's age
z----> Christina's age
we know that
Joe"s Age Is three times Aaron's age
----> equation A
Aaron is six years older than Christina
isolate the variable z
----> equation B
The sum of their ages is 149
----> equation C
solve the system by substitution
substitute equation A and equation B in equation C
solve for y
Combine like terms left side
Adds 6 both sides
Divide by 5 both sides
<em>Find the value of x</em>
---->
<em>Find the value of z</em>
----
therefore
Joe's age is 93 years
Aaron's age is 31 years
Christina's age is 25 years
