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!
<u>Jenny's age</u>: x
<u>Steve's age</u>: y
If<em> Jenny</em> was <em>four times older</em> than <em>Steve 5 years ago</em>, the equation would be:
y+12-4y=-15
<h2><em>
1#</em><em> </em></h2><h2>First, you add like terms:
</h2>
y+12-4y=-15
y-4y=-15-12
<h2><em>
#2 </em></h2><h2>
Now isolate the unknown variable:
</h2><h2>
</h2>
3y=-27
y=9
<h2><em>
3#</em><em> </em></h2><h2>But this was 5 years ago, and Jenny is 12 years older than Steve so add those two together:
</h2>
9+12=21
God Bless you!
