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