Answer:

Infinitely Many Solutions

Step-by-step explanation:

Since it's given that x = 3y + 4 we can use this in second expression

3×(3y+4) = 9y + 12 ➡ 9y + 12 = 9y + 12 add the like terms

9y - 9y = 12-12 ➡ 0 = 0 there's infinitely many solutions for second equation

Same goes for first equation.
