Question

解方程3.6＋x＝4.8 x－5.1＝7.9 x＋2.1＝5.6 6.5－x＝1.4

Answer 1

3.6＋x＝4.8
x=4.8-3.6
x=1.2

x－5.1＝7.9
x=5.1+7.9
x=13

x＋2.1＝5.6
x=5.6-2.1
x=3.5

6.5－x＝1.4
x=6.5-1.4
x=5.1
祝学习进步，望采纳~~

Answer 2

3.6＋x＝4.8
x=4.8-3.6
x=1.2

x－5.1＝7.9
x=7.9+5.1
x=13

x＋2.1＝5.6
x=5.6-2.1
x=3.5

6.5－x＝1.4
x=6.5-1.4
x=5.1

解方程,x－2.6＝4.7 x÷18＝3.6 2x＋3.4＝9.6 3x－6×12＝24 6.8x－0.8x＝0.48 5（6－x）＝35

追答

,x－2.6＝4.7
x=4.7+2.6
x=7.3

x÷18＝3.6
x=3.6*18
x=64.8

2x＋3.4＝9.6
2x=9.6-3.4
2x=6.2
x=3.1

3x－6×12＝24
3x=24+72
3x=96
x=32

6.8x－0.8x＝0.48
6x=0.48
x=0.08

5（6－x）＝35
6-x=7
x=6-7
x=-1
