Answer:

Sure, I'd be happy to help you solve these equations! Here are the solutions to the equations you provided:

1. -3x+7=-8x+47

Add 8x to both sides: 5x + 7 = 47

Subtract 7 from both sides: 5x = 40

Divide both sides by 5: x = 8

2. -13x+8=-8x-7

Add 13x to both sides: 5x + 8 = -7

Subtract 8 from both sides: 5x = -15

Divide both sides by 5: x = -3

3. 6x+7=3x+19

Subtract 3x from both sides: 3x + 7 = 19

Subtract 7 from both sides: 3x = 12

Divide both sides by 3: x = 4

4. 12x-8=10x+6

Subtract 10x from both sides: 2x - 8 = 6

Add 8 to both sides: 2x = 14

Divide both sides by 2: x = 7

5. -7x-4=-10x-10

Add 10x to both sides: 3x - 4 = -10

Add 4 to both sides: 3x = -6

Divide both sides by 3: x = -2

6. 7x-9=3x-5

Subtract 3x from both sides: 4x - 9 = -5

Add 9 to both sides: 4x = 4

Divide both sides by 4: x = 1

7. 3x-9=5x-3

Subtract 3x from both sides: -6 = 2x - 3

Add 3 to both sides: -3 = 2x

Divide both sides by 2: x = -3/2 or -1.5

8. 7x-1=5x+5

Subtract 5x from both sides: 2x - 1 = 5

Add 1 to both sides: 2x = 6

Divide both sides by 2: x = 3

9. -7x-2=-3x-14

Add 3x to both sides: -4x - 2 = -14

Add 2 to both sides: -4x = -12

Divide both sides by -4: x = 3

10. -3x-7=-8x-57

Add 8x to both sides: 5x - 7 = -57

Add 7 to both sides: 5x = -50

Divide both sides by 5: x = -10

I hope this helps! Let me know if you have any further questions.
