Answer 3

It looks like you've provided three mathematical expressions. Let's simplify each of them:

1. $(8x+3) - (4x-2) = 4x + 7$

   To simplify, first distribute the negative sign within the second parentheses:

   $8x + 3 - 4x + 2 = 4x + 7$

   Combine like terms on both sides:

   $4x + 5 = 4x + 7$

   Subtract $4x$ from both sides:

   $5 = 7$

   The equation is not valid. There is no solution.

2. $(5x+3) + (x-6) = 6x - 3$

   Distribute the addition signs within the parentheses:

   $5x + 3 + x - 6 = 6x - 3$

   Combine like terms on both sides:

   $6x - 3 = 6x - 3$

   Subtract $6x$ from both sides:

   $-3 = -3$

   The equation is true, but it doesn't provide a unique solution. Any value of $x$ would satisfy the equation.

3. $2x + 3 = 1.2x - 5$

   Subtract $1.2x$ from both sides:

   $2x - 1.2x + 3 = -5$

   Simplify the left side:

   $0.8x + 3 = -5$

   Subtract 3 from both sides:

   $0.8x = -8$

   Divide both sides by 0.8:

   $x = -10$

   The solution to the equation is $x = -10$.
