To solve the system of equations by substitution, we'll equate the two expressions for y and solve for x. Let's go through the process step by step:

Given equations:
1) y = -4x + 5
2) y = 3x - 16

Since both equations are set equal to y, we can set them equal to each other:
-4x + 5 = 3x - 16

Now, let's solve for x:
-4x - 3x = -16 - 5
-7x = -21
