Question

(7x-5)\4=3\8(2x-1)\6=(5x+1)\81\2 x-7=(9x-2)\61\5 x -1\2(3-2x

Answer 1

1)(7x-5)4=38

(7x-5)=32

7x=132

x=1314

2)(2x-1)6=(5x+1)8

(2x-1)3=(5x+1)4

4*(2x-1)=3*(5x+1)

8x-4=15x+3

x=-1

3) 12 x-7=(9x-2)6

3x-42=9x-2

6x=-40

x=-203

4)15 x -12(3-2x)=1

2x-5*(3-2x)=10

12x=25

x=2512

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

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

1-x=6

x=-5

6)17 (2x+14)=4-2x

(2x+14)=28-14x

16x=14

x=78

7)310 (200+x) - 210 (300-x) = 300×925

3(200+x) - 2(300-x) = 1080

600+3x-600+2x=1080

x=10805=216
