4.8x 11.7=4x%3.9解方程

4.8x+11.7=4x-3.9 4.8x-4x=-3.9-11.7 0.8x=-15.6 x = -19.5

4.8 x+3.4x=多少? 4.8x+3.4x =8.2x.

7.4X-3.9=4.8X+11.7 解 2.6X=15.6 X=6

解:4x=5.6十4.8 4x=10.4 x=2.6

x=(19.4+7)/4.8 x=26.4/4.8 . x=6.6

(1)4.8x÷2=1.2 4.8x÷2×2=1.2×2 4.8x=2.4 4.8x÷4.8=2.4÷4.8 x=0.5;(2)x:1.2=3:4 4x=1.2×3 4x÷4=3.6÷4 x=0.9;(3)13.56=x4 6x=13.5×4 6x÷6=54÷6 x=9.

4.8-4x=0.8-4x=0.8-4.84x=4x=1

发发汗反反复复v

x-0.7x=4.8 0.3x=4.8 x=4.8÷0.3 x=16
