Answer 1

1. ( x +7) = 10

x = 10-7

x = 3

2. (x-4)= 2

x = 2 + 4

x = 6

3. (x-10) = 12

x = 12+10

x = 22

4. 4(x -2)= 20

x -2= 20/4

x = 5+2

x = 7

5. x +6 /3 = 4

x = 4× 3 -6

x = 6

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

x = 3+2/5

x = 1 -1

x = 0

7. 2(x-2)+3= 12-3

x = 12-3-3+2/2

x = 8/2

x= 4

8. 2(x+1) -4 = 28÷ 7

2(x + 1) -4= 4

(x+1) = 4+4/2

(x+1) = 8/2

x = 4-1

x = 3
