I think it's the first option
To determine if the ordered pair (3 , -2) is a solution to 4x = 3y + 18,
plug in the point into the equation.
4x = 3y + 18 (Plug in 3 for "x", and plug in -2 for "y")
4(3) = 3(-2) + 18
12 = -6 + 18
12 = 12
This is a solution because in the end, the number is the same on both sides
