4x+3y=-12
2 answers:
Answer:
Infinit solutions
Step-by-step explanation:
Answer:
C infinitely many solutions
Step-by-step explanation:
multiply second equation by -3
-3 × (4x + 3y) = -12 ➡ -12x - 9y = 36 now add this to second equation
12x + 9y -12x -9y = -36 + 36 ➡0 = 0
we say there's infinite solutions because whatever value you write for x and/or y there will be a solution.
