Answer:

x = 3

Step-by-step explanation:

First distribute

2x + 4x - 4 = 2 + 4x

combine like terms

6x - 4 = 2 + 4x

continue

2x - 4 = 2

add 4 to both sides

2x = 6

divide both sides by 2

x = 3

2x+4(x-1)=2+4x.

Distribute the 4 into (x-1).

2x+4x-4=2+4x

Now add x’s

6x-4=2+4x

Solve for x.
(Move x to same side)

6x-4x-4=2+4x-4x.
Then do the same with -4.
2x-4+4=2+4.

2x=6

Divide 2 by both sides: 6/2

Your answer will be once divided : 3

Our equation is:

(x/-4)+11=5; we need to get x by itself in order to solve. Let's subtract 11 from both sides. (x/-4)=-6; let's now multiply both sides by -4. x=24; let's check to see if x is 24 by plugging it in.

24/-4=-6+11=5

So, x=24.

PLZ HELP FIFTY POINTS FOR WHOEVER HELPS I NEED THIS ASAP
mamaluj [8]

Answer:

x = 18

y = 54

Step-by-step explanation:

A straight line equals 180 degrees.

Since Lines CD and AB are straight, we can deduce that the angle 3x = 2x + angle AN.

Because there is a right angle, we can subtract 90 -72 = 18.

18 + 2x = 3x

18 = x

A straight line equals 180 degrees. Once we figure out that x = 18, we can figure out y by plugging in x and then subtracting your answer from 180 degrees.

I hope this was helpful to you! If it was, please consider rating, pressing thanks, and giving my answer 'Brainliest.' Have a great day!
