Using substitution or elimination
9x+3y=-7
y=-3x+4
2 answers:
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.
Answer:
No solution
Step-by-step explanation:
Plug in y=-3x+4 into 9x+3y=-7
9x+3(-3x+4)=-7 Distribute the 3
9x - 9x + 12 =-7 Combine like terms
12 =-7 This statement isn't true. Therefore this is system of has no solution. The lines do not intersect.
