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 :)
