Answer:
Hii!
I would like to help you!
The age of Jenny is 21 years
The age of Steve is 9 years
Step-by-step explanation:
Let's make their age into unknown variables so it's easier to understand!
Jenny's age: x
Steve's age: y
If Jenny was four times older than Steve 5 years ago, the equation would be:
y+12-4y=-15
1#
First, you add like terms:
y+12-4y=-15
y-4y=-15-12
#2
Now isolate the unknown variable:
3y=-27
y=9
3#
But this was 5 years ago, and Jenny is 12 years older than Steve so add those two together:
9+12=21
God Bless you!
