Ответ:
Infinate solutions
Step-by-step explanation:
You’d use elimination
so you’d want to get either the x values to be the same or the y values so in this case we can multiply the top equation (4x + 6y=7) by 3 and then subtract the two equations so, 3(4x+6y=7) = 12x + 18y = 21 which is the same as the other equation meaning If you subtract the two you get 0=0 which leaves you with infinite solutions.
