Answer:
present age of Rema=x
present age of Beena=y
after 6years
age of Rema=x+6
age of Beena=y+y
after 10 years
age of Rema=x+10
age of Beena=y+10
Step-by-step explanation:
x+6=4(y+6)
x+6=4y+24
x-4y=24-6
x-4y=18(equation 1)
x+10=3(y+10)
x+10=3y+30
x-3y 30-10
x-3y=20(equation 2)
x-3y =20
x-4y =18
y=-3y-(-4y)=20-18
y=-3y+4y=2
y=2
x=x-4y =18
x =x=4*2=18
x = x-8=18
x=18+8=26
present age of Rema= x=26
present age of Beena=y=2
