#

Your answer is right they just wanted u to solve it with simultaneous eqs

#

How would I go about doing that then

urban shoal Sep 13, 2023, 8:04 PM

#

You’d need to rearrange x + y = 18 for either x or y 5en sub that into the other eq

But what’s the other equation

urban shoal Sep 13, 2023, 8:23 PM

#

xy = 65
