What is the answer to number 4. I need help ASAP

Answer:
Step-by-step explanation:
Plug (4,-2) into each of the equations and test if the equation holds true.
(1) 3x + 6y = 0
3(4) + 6(-2) ≟ 0
12-12 = 0
(4,-2) is a solution to eq. (1)
:::::
(2) 2x + 10y = -12
2(4) + 10(-2) ≟ -12
8 - 20 = -12
(4,-2) is a solution to eq. (2)
You can finish from here.
