Ans : -28 & 59
So, first let one number =x and the other number = y
Equation : x+y = 31
x-y= 87 ( solve simultaneously)
The answer would either be (-3,5), (5,-3), (9,-7), or (-7,9). I forget where the <em>x </em>and <em>y</em> go, but those are your answer choices.
Answer:to solve the system in Example 4, you may find that the method of elimination is more efficient. ... this works, consider the following two systems of linear equations.
