Ответ:
-5x – 3y = 16
-5x – 3(x) = 16
Combine like terms:
-8x = 16
Divide (-8) from both sides of the equation:
x = -2
We have proven that “x” is equal to (-2). Using this knowledge, we can now substitute the known value of “x” into the second equation:
y = x
y = (-2)
We have now proven the values of both X and Y:
x = -2
y = -2
I hope this helps!
