let the two numbers be x and y
given x=y(2/5)
also given x+y=70
so substitute first equation in second
we get y(2/5)+y=70
so 2y+5y=350
hence y=50..
we then get x=20
so the two numbers are 20 and 50..
hope it helped..
mark me as brainliest ..please

bro it's wrong I think
because they said that 2 /5×x=70
eqd
we have taken x and y as any two numbers and you can replace x as y and y as x if you like
but only the thing is the two numbers are 20 and 50

then please mark me as brainliest
