Question

Use substitution to solve the system.
y = x + 6
y = 2x

Answer 1

Answer:

x = 6, y = 12

Step-by-step explanation:

y = x + 6 --- Equation 1

y = 2x --- Equation 2

Substitute y = 2x into Equation 1:

y = x + 6

2x = x + 6

2x - x = 6

x = 6 --- Equation 3

Substitute x = 6 into Equation 2:

y = 2x

y = 2(6)

y = 12
