Question

Linear Equations!

For questions 1–3, what is the solution of the system? Use substitution.

1. y = x + 6
y = 2x (1 point)
(6, 12)
(–12, –6)
(–6, –12)
(2, 4)

2. 3x + 2y = 7
–3x + 11 = y (1 point)
(6, –3)
(6, –7)
(-4, 19/2)
(5, –4)

3. 2x – y = –7
4x – y = –4 (1 point)
(–1.5, 4)
(1.5, 10)
(4, –1.5)
(–1.5, –2)
