Question

Y = 5x + 2

3x = –y + 10
What is the solution to the system of equations?

(–4, –18)
(–18, –4)
(7, 1)
(1, 7)

Answer 1

y = 5x + 2 . . . . . . . . . . (1)

3x = -y + 10 . . . . . . . . (2)

3x = -(5x + 2) + 10

3x = -5x - 2 + 10

3x + 5x = -2 + 10

8x = 8

x = 1

y = 5(1) + 2 = 5 + 2 = 7

Solution is (1, 7) The answer is (1,7)
