Hi there!
To solve this using substitution, we substitute the value of y in the equation.
5x + 8 = 8x + 9
Now, we simplify.
8 = 3x + 9
-1 = 3x
x = -1/3
We plug the value of x in,
y = 5 (-1/3) + 8
y = -1 2/3 + 8
y = 6 1/3
Hope this helps!
Answer: If I remember correctly, the answer should be <em>y=-2(3)^x. </em>
