Answer:
x = -10, y = -8
Step-by-step explanation:
We will use the method of elimination to find y.
Step 1: 5x - 8y = 14
-
5x - 7y = 6
Step 2: 0x - y = 8
Step 3: y = -8
Now, we have to substitute the y value into one of the original equations. In this case we will use the first equation which is 5x - 8y = 14.
5x - 8(-8) = 14
5x + 64 = 14
5x = - 50
x = -10
Just to make sure we have the right values, we will substitute both values into one of the equations.
5(-10) - 7(-8) = 6
-50 + 56 = 6
6 = 6 True
5(-10) - 8(-8) = 14
-50 + 64 = 14
14 = 14 True
Both of these values work, so they are the answers.
Hope this helps!
