Question

What is the solution of the system? Use substitution. y = x + 6 y = 2x

Answer 1

2x = x + 6
x = 6

Answer 2

A. (6, 12)
B. (–12, –6)
C. (–6, –12)
D. (2, 4)

Answer 3

y = 2(6)
y = 12

Answer 4

A

Answer 5

What is the solution of the system? Use substitution.

x = –2y + 10
–6y = 6x – 6
z = –3x + 10y

Answer 6

-6y = 6(-2y + 10) - 6


Solve for why then plug your answer into x = -2y+10. Once you have both x and y plug those numbers into the z equation.

Answer 7

y* not why lol
