解方程我最棒。
(1)4x+3.2x=36 (2)3.2x-1.6= 4.8
(3)(1+0.32)x=6.6 (4)x-18=24×0.2
(5)4×2.5+3x=31 (6)4.6x-8.7=17.98
(7)3.7x+6.5x=1.02 (8)0.6×(3+x)=12
(1)4x+3.2x=36
              7.2x=36
                   x=5
(2)3.2x-1.6= 4.8
               3.2x=6.4
                    x=2
(3)(1+0.32)x=6.6
                   1.32x=6.6
                         x=5
(4)x-18=24×0.2
         x-18=4.8
              x=22.8
(5)4×2.5+3x=31
               10+3x=31
                      x=7
(6)4.6x-8.7=17.98
              4.6x=9.28
                   x=5.8
(7)3.7x+6.5x=1.02
               11.2x=1.02
                     x=0.1
(8)0.6×(3+x)=12
                        3+x=20
                            x=17
