Answer 2

Answer:

1. 4x+12=24

=> 4x = 24-12

=> 4x = 12

=> x = 12/4

=> x = 3

2. 5x-4=21

=> 5x = 21+4

=> 5x = 25

=> x = 25/5

=> x = 5

3. 18-7x = -3

=> -7x = -3-18

=> -7x = -21

=> x = -21/-7

=> x = 3

4. 3(x-4)=21

=> 3x-12=21

=> 3x = 21+12

=> 3x = 33

=> x = 33/3

=> x = 11

5. 4(x-1)-(2x-5)=4

=> 4x-4-(2x-5)=4

=> 4x-4-2x+5=4

=> 2x+1=4

=> 2x=4-1

=> 2x=3

=> x=3/2
