solve the following by elimination method 2x+y=6,2x-y=-2 answer completely.

${ \color{aqua}{ \underbrace{ \underline{ \color{lime}{ \mathbb{✯꧁ ⋆᭄ SoLuTiOn⋆᭄꧂✯ }}}}}}$

$2x+y=6–———(1)$

$2x-y=-2–———(2)$

$substract \: 2nd \: equation \: from \: equation \: 1$

$2x + y = 6 \\ - 2x + y = 2$

___________

$2y = 8$

$y = \frac{8}{2}$

${\boxed {\boxed {y = 4}}}$

$put \: the \: y \: value \: in \: equation \: 1$

$2x + y = 6$

$2x + 4 = 6$

$2x = 6 - 4$

$2x = 2$

$x = \frac{2}{2}$

${\boxed {\boxed {x = 1}}}$
