Answer:
I believe that the answer is 9
Step-by-step explanation:
You just replace x with 3
Answer:
x = 6
Step-by-step explanation:
4(x - 3) + 5x - x^2
Substitute x with 3
4(3 - 3) + 5(3) - 3^2
Solve via PMDAS so Parenthesis first
4(0) + 5(3) - 3^2
Multiply then the rest is Self-Explanatory
15 - 9
x = 6
