Answer 2

To solve the given system of equations:

1. 5x + 4x = 72015z + 3z - 2z = 32027y - 5y = 9905y + 7y = 12015h - 8h = 31588t - 8t = 560

Let's simplify each equation step by step:

5x + 4x = 72015z 9x = 72015z x = (72015z)/9 x = 8001z

72015z + 3z - 2z = 32027y 72016z = 32027y z = (32027y)/72016 z = (71y)/160

9905y + 7y = 12015h 9912y = 12015h y = (12015h)/9912 y = (4015h)/3304

31588t - 8t = 560 31580t = 560 t = 560/31580 t = 0.0177

Therefore, the solution to the given system of equations is: x = 8001z y = (4015h)/3304 z = (71y)/160 t = 0.0177
