Question

1) x+7=18
2) x-5=10
3) 3x=24
4) x:2=8
5) 2x+3=9
6) 4x-9=x+21​

Answer 1

1) x + 7 = 18

x = 18 - 7

x = 11

2) x - 5 = 10

x = 10 + 5

x = 15

3) 3x = 24

x = 24 / 3

x = 8

4) x / 2 = 8

x = 2 . 8

x = 16

5) 2x + 3 = 9

2x = 9 - 3

2x = 6

x = 6 / 2

x = 3

6) 4x - 9 = x + 21​

4x - x =  21​ + 9

3x = 30

x = 30 / 3

x = 10
