Find two numbers whose sum is 9 and whose difference is -1
2 answers:
4 and 5 because four plus five is nine and five minus four is one
Answer:
4 and 5
Step-by-step explanation:
Make a system of equations:
x+y=9
x-y=-1
x=9-y
9-y-y=-1
9-2y=-1
-2y=-10
y=5
Since y=5, x must be 4 since 4+5=9 and 4-5=-1
