I really REALLY need the work for these 5 math problems, I can't wrap my brain around how to understand how to do this still and I have a big test soon :')

1. x + 4 = 2x -6
2. 4(6x + 3) = 2 (4x - 2)
3. 2x + 5 = 21
4. 4(x + 6) - 11 = 25
5. 5(3x + 4) = 2(5x + 7)​

Answer:

1.. x  = 10

2.x = -1

3. x = 8

4. x = 3

5. x = - 6/5

Step-by-step explanation:

1.

Move terms

x - 2x + 4 = -6

x - 2x = -6 -6

-x = -6 -4

-x = -10;

x = 10;

2.

24x + 12 = 8x -4

24x - 8x = -4 - 12

16x = -16

x = -1

3.

2x = 21-5

2x = 16

x = 8

4.

4x + 24 - 11 = 25

4x + 13 = 25

4x = 25 - 13

4x = 12

x = 3

5.

15x + 20 = 2(5x + 7)

15x + 20 = 10x + 14

15x - 10x = 14 - 20

5x = -5

x = - 6/5
