Let's solve this problem step-by-step.
STEP-BY-STEP EXPLANATION:
We will be using simultaneous equations to solve this problem.
We will convert information from the problem into two equations as displayed below:
Let F = Freddie
Let E = Elena
Equation No. 1 -
F = 5E
Equation No. 2 -
F + 4 = 3E + 8
To begin with, we will substitute the value of ( F ) from the first equation into the second equation to solve for ( E ).
Equation No. 2 -
F + 4 = 3E + 8
( 5E ) + 4 = 3E + 8
5E - 3E = 8 - 4
2E = 4
E = 4 / 2
E = 2
From this, we will substitute the value of ( E ) from the second equation into the first equation to solve for ( F ).
Equation No. 1 -
F = 5E
F = 5 ( 2 )
F = 10
FINAL ANSWER:
Therefore, Freddie is 10 years old and Elena is 2 years old.
Hope this helps! :)
Have a lovely day! <3
