2.5x + 3.5x + 8 = 6.2x -10
6x + 8 = 6.2x -10
-0.2x + 8 = -10
-0.2x = -18
x = 90
5x + 25y = 60....multiply by -3
3x + 15y = 42....multiply by 5
-------------------
-15x - 75y = - 180 (result of multiplying by -3)
15x + 75y = 210 (result of multiplying by 5)
-------------------add
0 = 30...incorrect.....this system has no solutions
