To solve this equation, we have to use the distributive property to multiply 5y through the parentheses.
-45y - 15y^2 = 13
-15y^2 - 45y - 13 = 0
15y^2-45y-13=0

Step-by-step explanation:
In this problem, all we have to do is replace x and y with the values we've been given.
It can be helpful to think of 3x as 3 * x (which is the same exact thing), so I'll write it out that way.
3*x - 4*y
(replace)
3*4 - 4*3
(multiply (doing this step first because of PEMDAS))
12 - 12
(subtract)
0
