Solve the system of equations using substitution.

Answer:
( [tex]\frac{1}{3}[/tex], 3 )
Step-by-step explanation:
Given the 2 equations
y = 9x → (1)
6x - y = - 1 → (2)
Substitute y = 9x into (2)
6x - 9x = - 1, that is
- 3x = - 1 ( divide both sides by - 3 )
x = [tex]\frac{1}{3}[/tex]
Substitute x = [tex]\frac{1}{3}[/tex] into (1) for corresponding value of y
y = 9 × [tex]\frac{1}{3}[/tex] = 3
Solution is ( [tex]\frac{1}{3}[/tex], 3 )
