How am I supposed to solve this? I know how to do the equations but I don't know why there are only 2 places to put an answer for X and Y when there are 2 equations. Both equations have an X and a Y so that means there are 4 X and Y answers.

Question
Answer:
Answer:x = 1y = -4Step-by-step explanation:We will multiply the 2nd equation by 4 first:4 * [-x + y = -5]-4x + 4y = -20Now we will add this equation with 1st equation given. Shown below:4x + 3y = -8-4x + 4y = -20---------------------7y = -28Now, we can solve for y easily:7y = -28y = -28/7y = -4Now, we take this value of y and put it in 1st original equation and solve for x:4x + 3y = -84x + 3(-4) = -84x - 12 = -84x = -8 + 124x = 4x = 4/4x = 1So, this is the only solution to this problem ( 1 intersection point at x = 1 and y = -4)
