Answer:
4x - 4
Step-by-step explanation:
Combine like terms. Like terms are terms with the same variable as well as the same amount of variables:
6x - 2x + 2 - 1 - 4 - 3 + 2
(6x - 2x) = 4x
(2 - 1 - 4 - 3 + 2) = (2 + 2) + (-1 - 4 - 3) = (4) + (-8) = -4
4x - 4 is your answer.

f(3) = 1
substitute x = 3 into f(x)
f(3) = (2 × 3) - 5 = 6 - 5 = 1
Answer:

Answer: 7
Work: So, the goal is to get z alone, so we are going to add 85 on both sides, cancelling on the side it's currently on. So, the new equation is going to be 25z = 175. Then, to get z even more lonely, we are going to divide 25 on both sides, and again cancelling it on the side it's currently on. So, the answer is z = 7. I hope this helps, and Happy Holidays! :)
