Answer 1

1) x=2
2) x=-10
3) x=2
4) m=-8

Answer 2

It looks like you've provided a set of equations. I can help you solve them one by one:

1. $3x = x + 4$

   To solve for $x$, subtract $x$ from both sides:

   $3x - x = 4$
   $2x = 4$
   $x = 2$

2. $0.5x + 3 = 0.2x$

   To solve for $x$, subtract $0.2x$ from both sides and then subtract 3 from both sides:

   $0.5x - 0.2x = -3$
   $0.3x = -3$
   $x = -10$

3. $4x - 8 = 6 - 3x$

   Add $3x$ to both sides and add 8 to both sides:

   $4x + 3x = 6 + 8$
   $7x = 14$
   $x = 2$

4. $7m + 1 = 8m + 9$

   Subtract $7m$ from both sides:

   $7m - 7m + 1 = 8m - 7m + 9$
   $1 = m + 9$
   $m = -8$

So, the solutions for the variables are:

1. $x = 2$
2. $x = -10$
3. $x = 2$
4. $m = -8$
