Hi!

The answer should be third option.

$20+4j\ge 2\left(j+20\right)$

$20+4j\geq 2j+40$

$20+4j-20\geq 2j+40-20$

$4j\geq 2j+20$

$4j-2j\geq 2j+20-2j$

$2j\geq 20$

$\frac{2j}{2}\geq \frac{20}{2}$

$Answer ---> j\geq 10$

Explanation: First you had to subtract by the 20 from both sides. Then simplify it gave us 4j ≥ 2j+20. You can also subtract by the 2j from both sides. Then simplify its going to be 2j≥20. Next, you can also divide by 2 from both sides, and it gave us the answer is j≥10 is the right answer. Hope this helps! And thank you for posting at here on Brainly. And have a great day. -Charlie

X+y=8 solve by substitution and Y=3x with substitution too

inna [77]

Answer:

x=2

Step-by-step explanation:

Convert the Y to 3x since we know that y=3x.

You would get x+3x=8.

Add the x and 3x to get 4x

Then, you would get 4x=8.

Divide by 4 on both sides to get x=2.
