Question

（1）5+2x=1 (2)8-x=3x+2 (3)10x-3=9 (4)6x-7=4x-5 (5)1/2x-6=3/4x

Answer 1

（1）5+2x=1

2x=1-5

2x=-4

x=-2

(2)8-x=3x+2

3x+x=8-2

4x=6

x=3/2

(3)10x-3=9

10x=9+3

10x=12

x=6/5

(4)6x-7=4x-5

6x-5x=7-5

x=2

(5)1/2x-6=3/4x

3/4x-1/2x=-6

1/4x=-6

x=-24

(6)1-3/2x=3x+5/2

3x+3/2x=1-5/2

9x/2=-3/2

9x=-3

x=-1/3
