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
