Answer:
there is no answer
Explanation:
Picture attached
(a proof for that would be drawing two graphs, we will see that the two lines won't cut each other at any point as we knew (cause two slopes are equal))
a=3x-y
x=y/3+14/9
9x-3y=14 add 3y to both sides
9x=14+3y the equation is in standard format
and you can use Microsoft math solver to help solve and show how to solve then step by step
