Question

如题所述

Answer 1

48X+54=18X+60
30x=6
x=1/5

5+3X=17.6-X
4x=12.6
x=3.15

0.125x(X+3)=1
x+3=8
x=5追问

2X+20=4X-24 6x(X-1)=7x(X-3)

追答

2X+20=4X-24
44=2x
x=22

6x(X-1)=7x(X-3)
6x-6=7x-21
21-6=7x-6x
x=15

Answer 2

48X+54=18X+60
48X-18X=60-54
30X=6
X=0.2

5+3X=17.6-X
3X+X=17.6-5
4X=12.6
X=3.15

0.125x(X+3)=1
X+3=1÷0.125
X+3=8
X=8-3
X=5追问

2X+20=4X-24 6x(X-1)=7x(X-3)

追答

2X+20=4X-24
4X-2X=20+24
2X=44
X=22

6x(X-1)=7x(X-3)
6X-6=7X-21
7X-6X=21-6
X=15

Answer 3

48X+54=18X+60
30X=6
X=0.2

5+3X=17.6-X
4X=12.6
X=3.15

0.125x(X+3)=1
X+3=8
X=8-3
X=5

Answer 4

48x+54=18x+60
解：30x=6
x=0.2
5+3x=17.6-x
解：4x=12.6
x=3.15
