Question

The sum of two numbers are -17 and their difference is 41

Answer 1

X = 12 Y = -29

Explanation:

X+Y= -17

X-Y=41

Solve for y in first equation

Y=-17-x plug y into the 2nd equation

X-(-17-x)=41

X+17+x=41

2x=41-17

2x=24

X=12

Y=-17-(x)

Y=-17-12

Y=-29

X+Y=-17

12+-29=-17

X-Y=41

12- -29=41
