Question

slove the following pair of linear equations by graph method 2x+y=6 and 2x-y+2=0​

Answer 1

Answer:

$2x + y = 6 \\ \\ y = 6 - 2x \\ \\ 2x - y + 2 = 0 \\ \\ 2x - (6 - 2x) + 2 = 0 \\ \\ 2x - 6 + 2x + 2 = 0 \\ \\ 4x - 4 = 0 \\ \\ { \large{ \pink{x = 1 }}}\\ \\ y = 6 - 2x \\ \\ y = 6 - 2 \times 1 \\ \\ y = 6 - 2 \\ \\ { \large{ \orange{y = 4}}}$
