Step-by-step explanation:

Step 1: Define

y = 23x - 4

x = 18

Step 2: Evaluate

1. Substitute x:                    y = 23(18) - 4
2. Multiply:                           y = 414 - 4
3. Subtract:                          y = 410

Answer 2

Answer:

y = 410

Step-by-step explanation:

y = 23x - 4    If x = 18

y = (23*18) - 4

y = 414 - 4

y = 410
