Question

Find the solution to the system of equations by using either graphing and substitution y = 6 - x and y = x - 2

pls explain ur answer.

Answer 1

x = 4, y = 2

Explanation:

y = 6 - x

y = x - 2

Substitute the value for y in the first equation into the second.

So we get:

6 - x = x - 2

-x - x = -2 -6

-2x = -8

x = 4

Plug this into second equation:

y = 4 - 2 = 2.

Check these results in equation 1:

y = 6 - x

2 = 6 - 4 = 2

- so correct.
