Answer 2

It looks like you've provided several equations. I'll solve each of them for you:

1. 4x + 3 = x - 9 Subtract x from both sides: 4x - x + 3 = -9 3x + 3 = -9 Subtract 3 from both sides: 3x = -9 - 3 3x = -12 Divide by 3: x = -12 / 3 x = -4

2. 2x - 19 = 8 - x Add x to both sides: 2x + x - 19 = 8 3x - 19 = 8 Add 19 to both sides: 3x = 8 + 19 3x = 27 Divide by 3: x = 27 / 3 x = 9

3. 7x + 3 = 3x + 27 Subtract 3x from both sides: 7x - 3x + 3 = 27 4x + 3 = 27 Subtract 3 from both sides: 4x = 27 - 3 4x = 24 Divide by 4: x = 24 / 4 x = 6

4. 3x - 7 = 2x + 3 Subtract 2x from both sides: 3x - 2x - 7 = 3 x - 7 = 3 Add 7 to both sides: x = 3 + 7 x = 10

5. 42 - x = 2x + 9 Add x to both sides: 42 - x + x = 2x + 9 + x 42 = 3x + 9 Subtract 9 from both sides: 42 - 9 = 3x 33 = 3x Divide by 3: x = 33 / 3 x = 11

6. 20 + 3x4 - x It's not clear what you mean by "3x4." If you meant 3 times 4, then it's 12. The equation would be: 20 + 12 - x 32 - x

So, the solution for this equation is simply 32 - x.

If you meant something else by "3x4," please clarify, and I'll help you solve the equation accordingly.
