Answer 2

It seems like you have a system of equations that you'd like to solve. Let's break it down step by step:

1. 3(t - 4) + 6(t - 2) = 3(t + 2) + 56
2. -2(x + 9) = 36
3. 4(3 - 4) = 3x + 11

Let's solve each equation separately:

1. Expand and simplify the first equation: 3(t - 4) + 6(t - 2) = 3(t + 2) + 56

   3t - 12 + 6t - 12 = 3t + 6 + 56

   Combine like terms on both sides:

   9t - 24 = 3t + 62

   Move the 3t term to the left side by subtracting 3t from both sides:

   9t - 3t - 24 = 62

   Simplify:

   6t - 24 = 62

   Add 24 to both sides:

   6t = 62 + 24

   6t = 86

   Divide by 6:

   t = 86 / 6

   t = 43/3

2. Solve the second equation: -2(x + 9) = 36

   Distribute the -2 on the left side:

   -2x - 18 = 36

   Add 18 to both sides:

   -2x = 36 + 18

   -2x = 54

   Divide by -2:

   x = 54 / (-2)

   x = -27

3. Solve the third equation: 4(3 - 4) = 3x + 11

   Simplify the left side:

   4(-1) = 3x + 11

   -4 = 3x + 11

   Subtract 11 from both sides:

   -4 - 11 = 3x

   -15 = 3x

   Divide by 3:

   x = -15 / 3

   x = -5

So, the solutions to the system of equations are:

• t = 43/3
• x = -27
