如何将简易方程化简?
6a+13a 6x-28-2.5x+30.5
8a-(5a+8) (5x+7)-(4x+0.18)

如何将简易方程化简?6a+13a 6x-28-2.5x+30.58a-(5a+8) (5x+7)-(4x+0.18)
6a+13a=19a 6x-28-2.5x+30.5=3.5x+2.5 8a-(5a+8)=8a-5a-8=3a-8
(5x+7)-(4x+0.18)=5x+7-4x-0.18=x+6.82

19a 3.5x+2.5
3a-8 x+6.82

6a+13a=19a
6x-28-2.5x+30.5=3.5x+2.5
8a-(5a+8) =3a-8
(5x+7)-(4x+0.18)=x+6.82
