x^2-15x-2x+30
x(x-15)-2(x-15)
(x-2)(x-15)
x(x-15)-2(x-15)
(x-2)(x-15)
x+5=2(y+5)
we get
x=2y+5
substitute x equal to 2 Y + 5 in equation 1
2y+5=3y-10
y is equals to 15
substitute the value of x in equation one
we will get X is equals to 35
rams present age is 35 and shyam's present age is 15
here is the answer bro
