Question

giúp mik nha

4.10-x:2=1

5.x:4+3*2=7

6.2:x+5=6

7.2*x*3*5=30

8.2*x:10*2=1

9.18:x-5*2=8

10.5*5-2:x=24

Answer 1

a) 10 - x : 2 = 1

x: 2 = 9

x = 18

b) x:4 + 3 x 2 = 7

x:4 + 6 = 7

x:4 = 1

x = 4

c) 2: x + 5 = 6

2: x = 1

x = 2

Answer 2

+4.10-x:2=1

40-x:2=1

     x:2=40-1

     x:2=39

    x:2=19,5

+5.x:4+3*2=7

5.x:4+6=7

5.x:4=7-6=1

5.x=1.4=4

x=4:5

x=0,8

+6.2:x+5=6

12:x=6-5

12:x=1

x=12:1

x=12

+7.2*x*3*5=30

14.x.15=30

14.x=2

x=2:14

x=1/7

+8.2*x:10*2=1

16.x:20=1

16.x=20

x=20:16

x=1,25

9.18:x-5*2=8

10.5*5-2:x=24

Answer 3

d) 2 * x * 3 * 5 = 30

x * 30 = 30

x = 1

e) 2 * x : 10* 2 = 1

2*x * 1/10 * 2 = 1

2/5 * x = 1

x = 5/2

g) 18 : x - 5*2 = 8

18 : x - 10 = 8

18 : x = 18

x = 1

h) 5*5 -2 : x = 24

25 - 2:x = 24

2:x = 1

x = 2
