In 4 years, sravani will be 3 times as old as Makayla is currently. three years ago, sravani was 4 times as old as Makayla was then. what are both of their resent ages?

Answer 1

X - Sravani
y - Makayala

$x+4=3y\\ x-3=4(y-3)\\\\ x=3y-4\\ x=4y-12+3\\\\ x=3y-4\\ x=4y-9\\\\ 3y-4=4y-9\\ 4y-3y=-4+9\\ y=5\\\\ x=3\cdot5-4\\ x=15-4\\ x=11$

Sravani - 11
Makayla - 5
