Question

How much is the sum of 23 and 48 less than their product?

Answer 1

Hlw mate!!

Our two equations are:x+y=16xy=55

Rewriting equation (1) in terms of just y= something, we get:

y=16−x

Substituting this into equation (2) leaves us:x(16−x)=5516x−x2=55⟹x=5  or  11

which can be easily seen by factoring or using the quadratic formula. It follows that y=11|x=5 and y=5|x=11.

Thus your solutions in terms of (x,y) are (5,11) and (11,5).
