PLEASE HELP ASAP 50 POINTS AND BRAINLYEST

Answer:

Either x = 3, y = 2

(3,2) is your answer.

Step-by-step explanation:

2x +y = 8 (1)

y = - x+ 5 (2)

Put equation (2) into equation (1). Use the y value in (2) to go into the y value in (1).

2x - x+5 = 8 Combine the x values

x + 5 = 8 Subtract 5 from both sides

x + 5-5 = 8-5

x=3

Now go back to (2). Put x in for the value of -x. Watch the sign.

y = -3+ 5

y = 2

So the answer is (3,2)
