First you have to isolate one of the equations for y=mx+b.
Then substitute the equation is made into the first equation
Answer:
y = 9 - 3x
Step-by-step explanation:
9x + 3y - 27 = 0 ( add 27 to both sides )
9x + 3y = 27 ( subtract 9x from both sides )
3y = 27 - 9x ( divide through by 3 )
y = 9 - 3x
