C. y = 5x
Explanation:
(5 - 15) / (1 - 3)
-10 / -2
5
Answer:
(x, y, z) = (-2, 5, 1) solve the equation by using substitution as it is easier.
13x-9=16
+9 +9
13x= 25
---- -----
13x 13x
x=1.92
Add nine to both sides of equation to cancel out the negative nine. Then, divide both sides by 13, which will result in the answer listed above.
