Which of the following equations has a solution of negative 8
X + 3 = -11
X - 10 =2
× - 4 = - 12
X- 8=0
The equation that has a solution of negative 8 is:
X + 3 = -11
To determine which of the following equations has a solution of negative 8, we can substitute -8 for the variable X in each equation and see which one results in a true statement.
1. X + 3 = -11:
Substituting -8 for X:
-8 + 3 = -11
-5 = -11
The statement is false. -8 is not a solution for this equation.
2. X - 10 = 2:
Substituting -8 for X:
-8 - 10 = 2
-18 = 2
Again, the statement is false. -8 is not a solution for this equation either.
3. X - 4 = -12:
Substituting -8 for X:
-8 - 4 = -12
-12 = -12
This time, the statement is true. -8 is a solution for this equation.
4. X - 8 = 0:
Substituting -8 for X:
-8 - 8 = 0
-16 = 0
Once again, the statement is false. -8 is not a solution for this equation.
Therefore, the equation X - 4 = -12 has a solution of -8.
To find out which equation has a solution of -8, we need to plug -8 into each equation and see which one makes the equation true.
1. X + 3 = -11
To check if -8 is a solution to this equation, we substitute -8 for X:
-8 + 3 = -11
-5 = -11
The equation is not true when X = -8.
2. X - 10 = 2
To check if -8 is a solution to this equation, we substitute -8 for X:
-8 - 10 = 2
-18 = 2
Again, the equation is not true when X = -8.
3. X - 4 = -12
To check if -8 is a solution to this equation, we substitute -8 for X:
-8 - 4 = -12
-12 = -12
This equation is true when X = -8.
4. X - 8 = 0
To check if -8 is a solution to this equation, we substitute -8 for X:
-8 - 8 = 0
-16 = 0
This equation is not true when X = -8.
Therefore, the equation that has a solution of -8 is X - 4 = -12.
