Question

Solve the system: y = x + 2 , y = -3x + 10 . Answer as an ordered pair. (x,y)

Answer 1

(2,4)

Explanation:

y = x + 2

y = -3x + 10

y = y

x + 2 = -3x + 10

x + 3x + 2 = 10

4x + 2 = 10

4x = 10 - 2

4x = 8

x = 8 ÷ 4

x = 2

y = x + 2

y = (2) + 2

y = 4

Answer 2

Explanation: let x = 0. Then y = -2. The ordered pair is a solution to 2x - 5y=10
