X+y=0.5<br> x-y=1<br> elimination meathod
user100 [1]

Answer:

x=0.75, y=-0.25

Step-by-step explanation:

We can add the two equations to eliminate y and solve for x.

x+y+x-y=0.5+1

2x=1.5

x=0.75

Now, we can find for y by using substitution:

x+y=0.5 (given)

0.75+y=0.5

y=-0.25

Hope this helps :)
