Sagot :

Answer:

hi may I know the instructions here please, so I can help you..

but if you are looking for the value of x, below is the solution :

1.) x+6=12

x+6-6=12-6

x=6

2.) 2(x+7)=28

2x+14=28

2x+14-14=28-14

2x=14

2x/2=14/2

x=7

3.) x-8>4

x-8+8>4+8

x>12

x can be any number greater than 12 (like 13, 14, 15 and so on.. )

4.) 3x+5<23

3x+5-5<23-5

3x<18

3x/3<18/3

x<6

x can be any number less than 6 (like 5, 4, 3, 2, 1, 0 and negative numbers)

5.) -10 > -5

This mathematical statement is not true because -5 is greater than -10. Hence it should be written as -10 < -5
