—3x + 1/3y = 12
2y = 18х + 72

I need the answer ASAP how many solutions and the answer

Infinite solutions or all real numbers

Step-by-step explanation:

divide the bottom equation by 2 then

-3x +1/3 (9x + 36) = 12

-3x + 3x + 12 = 12 (distribute the 1/3 to the terms in the parentheses)

12 = 12

Infinite solutions
