x+y=10 x-y=2 solve using elemination(allgerbra 2)

6=x 4=y  

hmm... well lets see

x+y=10

x-y=2

*thinking*

x=6

y=4

x+y=10 x-y=2 solve using elemination(allgerbra 2) ?

$$\\ \frac{(x+y)\textcolor[rgb]{1,0,0}{+}(x-y)}{2} = x = \frac{10+2}{2} = \frac{12}{2} = 6 \\ \frac{(x+y)\textcolor[rgb]{1,0,0}{-}(x-y)}{2} = y = \frac{10-2}{2} = \frac{8}{2} = 4$$
