Answer 2

To solve the given equations, let's go step by step:

1. 8 - y = 1221 - (-x) Simplifying the equation, we have: 8 - y = 1221 + x

2. -15 + y - 14 = -2315 - x Simplifying the equation, we have: -29 + y = -2315 - x

3. -x = -49(-51) Simplifying the equation, we have: -x = 2499

4. -x = 60 Simplifying the equation, we have: x = -60

Now, let's solve the equations one by one:

1. 8 - y = 1221 + x Rearranging the equation, we have: x = 8 - y - 1221

2. -29 + y = -2315 - x Rearranging the equation, we have: x = -29 + y + 2315

3. -x = 2499 Rearranging the equation, we have: x = -2499

4. -x = 60 Rearranging the equation, we have: x = -60

Now, let's substitute the values of x into the equations and solve for y:

1. x = 8 - y - 1221 Substituting x = -2499, we have: -2499 = 8 - y - 1221 Simplifying the equation, we get: -2499 = -y - 1213 Rearranging the equation, we have: -y = -2499 + 1213 Simplifying further, we get: -y = -1286 Dividing both sides by -1, we get: y = 1286

2. x = -29 + y + 2315 Substituting x = -2499, we have: -2499 = -29 + y + 2315 Simplifying the equation, we get: -2499 = y + 2286 Rearranging the equation, we have: y = -2499 - 2286 Simplifying further, we get: y = -4785

Therefore, the solutions to the given equations are: x = -60 y = 1286
