Question

Use substitution to solve the system of linear equations. In your final answer, include all of your work.

Answer 1

thank you

Explanation:

Answer 2

No solutions

Explanation:

Substitute
`3x-9` instead of
`y` into the second equation:

`x-(1)/(3)(3x-9)=-3`

Use distributive property to open the brackets:

`x-(1)/(3)\cdot 3x+(1)/(3)\cdot 9=-3\\ \\x-x+3=-3\\ \\3=-3`

This equality is false (3 is not equal to -3), so the system of two equations has no solutions.
