Question

Ok another justification one
What is the justification for each step in solving the inequality −7(3 + 8𝑥) + 5𝑥 ≤ 1 − 62𝑥?

−7(3 + 8𝑥) + 5𝑥 ≤ 1 − 62𝑥
−21 – 56𝑥 + 5𝑥 ≤ 1 – 62𝑥
−21 – 51𝑥 ≤ 1 – 62𝑥
−22 – 51𝑥 ≤ −62𝑥
−22 ≤ −11

Answer 1

Ohh okay. Lemme see :)

Answer 2

−7(3 + 8𝑥) + 5𝑥 ≤ 1 − 62𝑥 ~Given
−21 – 56𝑥 + 5𝑥 ≤ 1 – 62𝑥 ~Distributive
−21 – 51𝑥 ≤ 1 – 62𝑥 ~Addition
−22 – 51𝑥 ≤ −62𝑥 ~Subtraction
−22 ≤ −1𝑥 ~Addition

I forget the full names of the proof side (right side) but that should help you find the right ones if there is a list or something. It should be right :)

Answer 3

ok thank you and this is the last justification Q

Answer 4

oh and catch *throws medal*

Answer 5

^_^ Anytime
