You can put this solution on YOUR website!
At present:
Let x= Marilou's Age
5x=Perla's Age
Ten yrs from now:
3%28x%2Bhighlight%2810%29%29=5x%2Bhighlight%2810%29
3x%2B30=5x%2B10
5x-3x=30-10
2x=20 ------>cross%282%29x%2Fcross%282%29=cross%2820%2910%2Fcross%282%29
highlight%28x=10yrs%29, MArilou's Age
5%2A10=highlight%2850yrs%29, Perla's Age
Check, in 10 yrs,
M%2B10=10%2B10=highlight%2820yrs%29
P%2B10=50%2B10=highlight%2860yrs%29
*Perla is 3 times as old as Marilou
Thank you,
