Which system is equivalent to the system shown and could be used to solve the system of equations correctly using the eliminatio
n method? 5x – 4y = 18 x + 3y = -4
1 answer:
Answer:
The solution is (2, -2)
Step-by-step explanation:
In order to solve this, multiply the second equation by -5 and then add through.
5x - 4y = 18
-5x - 15y = 20
------------------
-19y = 38
y = -2
Now that we have the value of y, we can solve for x.
x + 3y = -4
x + 3(-2) = -4
x - 6 = -4
x = 2
