Answer:

9a. 10(4x+1)+15(2x-1)-6(3x-7)/30=6

40x+10+30x-15-18x+42=6×30

52x-37=180

52x=180+37

52x=217

x=217/52

x=4.17

b.25/6×25x/24=0

x-4=0

x=4

9a. 2 by 6 - 19 is equal to 2 by 2 x minus 11

2 into 2 x minus 11 is equal to 2 into 6 - 19

4 x minus 22 is equal to 12 x - 38

4 x minus 12 x is equal to - 38 + 22

-8 x is equal to minus 16

8 x is equal to 16

x is equal to 16 by 8

x is equal to 2

b. 2 into 3 x minus 1 minus 2 X + 1 by 7 x minus 2 is equal to 1 by 2

6 x minus 2 minus 2 x minus 1 by 7 x minus 2 is equal to 1 by 2

6 x minus 2 minus 2 x minus 1 is equal to 1 by 2 into 7 x minus 2

6 x minus 2 minus 2 x minus 1 is equal to 7 by 2 x minus 1

6 x minus 2 x minus 7 by 2 x is equal to minus 1 + 2 + 1

4 x minus 7 by 2 x is equal to 1 + 1

8 x minus 7 x by 2 is equal to 2

8 x minus 7 x is equal to 2 into 2

8 x minus 7 x is equal to 4

x is equal to 4
