To find an equation that has a solution of -7, we would substitute -7 into each equation and see which equation gives a true statement.
Let's substitute -7 into each equation:
1) 4(-7) - 23 = 5
Simplifying, we get:
-28 - 23 = 5
-51 = 5
This is not true, so this equation does not have a solution of -7.
2) -(-7) + 3 = - 4
Simplifying, we get:
7 + 3 = -4
10 = -4
This is not true, so this equation does not have a solution of -7.
3) -3(-7) - 8 = - 29
Simplifying, we get:
21 - 8 = -29
13 = -29
This is not true, so this equation does not have a solution of -7.
4) 5(-7) + 11 = - 24
Simplifying, we get:
-35 + 11 = -24
-24 = -24
This is true, so this equation has a solution of -7.
Therefore, the equation that has a solution of -7 is 5x + 11 = -24.
Which of the following equations has a solution of -7? (1 point)
O 4x - 23 = 5
- x + 3 = - 4
O - 3x - 8 = - 29
O 5x + 11 = - 24
