Try this:

if x=13 it means 'one solution'; the only point;

if 0=13 it means 'no solution'; wrong equation = no points;

if 0=0 it means 'many solutions'; no variable in the equation = much points.

Finally:

System #1 - one solution;

System #2 - no solution;

System #3 - many solutions.

Please anwer what is X and give the explantion,how did you get the answer.ASAP
grigory [225]

We can solve x through simple algebra.

x + 5 = 2

x = 2 - 5

x = -3

x - 10 = 22

x = 22 + 10

x = 12

x - 27 = 8 + 10

x - 27 = 18

x = 18 + 27

x = 45

-11 + x + (-48) = 25

-11 + (-48) + x = 25

-59 + x = 25

x = 25 + 59

x = 84

x - (-16) = 12 + 13

x + 16 = 25

x = 25 - 16

x = 9

Tip: As you can see, the number sign changes as they shift from left to right (ex. -59 to +59).
