To determine which equation has a solution of -3, we substitute -3 into each equation and check if it satisfies the equation.
1) - x + 3 = -13
When we substitute -3 into this equation, we have:
- (-3) + 3 = -13
3 + 3 = -13
6 = -13
This equation does not have a solution of -3.
2) 5x + 10 = -5
When we substitute -3 into this equation, we have:
5(-3) + 10 = -5
-15 + 10 = -5
-5 = -5
This equation has a solution of -3.
3) 4x + 6 = 11
When we substitute -3 into this equation, we have:
4(-3) + 6 = 11
-12 + 6 = 11
-6 = 11
This equation does not have a solution of -3.
4) 8x - 4 = 20
When we substitute -3 into this equation, we have:
8(-3) - 4 = 20
-24 - 4 = 20
-28 = 20
This equation does not have a solution of -3.
Therefore, the equation 5x + 10 = -5 has a solution of -3.
Which of the following equations has a solution of -3? * 2 points - x + 3 = -13 5x + 10 = -5 4x + 6 = 11 8x - 4 = 20
