Answer 2

It looks like you have a system of three linear equations with one variable, "x." To find the value of "x," you can solve each equation step by step. Here's how you can do it:

1. Solve the first equation: 15 - x = 8

   Subtract 15 from both sides of the equation to isolate "x": -x = 8 - 15 -x = -7

   Now, multiply both sides by -1 to solve for "x": x = 7

2. Solve the second equation: 13 - x = 7

   Subtract 13 from both sides of the equation to isolate "x": -x = 7 - 13 -x = -6

   Again, multiply both sides by -1 to solve for "x": x = 6

3. Solve the third equation: x + 40 = 47

   Subtract 40 from both sides of the equation to isolate "x": x = 47 - 40 x = 7

So, the value of "x" is 7, and it is the solution to all three equations.
