Using substitution or elimination <br><br> 9x+3y=-7<br> y=-3x+4
-Dominant- [34]

Answer:

No solution

Step-by-step explanation:

If we substitute the y into the equation, we get 9x+3(-3x+4)=-7

If we distribute the 3, we get 9x-9x+12=-7

This then cancels out both 9x's and we are left with 12=-7, making it no solution.
