Which of the following equations has a solution of −7?(1 point)
4x−23=5
5x+11=−24
−x+3=−4
−3x−8=−29
To determine which equation has a solution of -7, we need to substitute -7 into each equation and check if it holds true.
1) 4x - 23 = 5
Substituting -7: 4(-7) - 23 = -28 - 23 = -51. This equation does not hold true, so it is not the correct answer.
2) 5x + 11 = -24
Substituting -7: 5(-7) + 11 = -35 + 11 = -24. This equation holds true, so it is a possible solution.
3) -x + 3 = -4
Substituting -7: -(-7) + 3 = 7 + 3 = 10. This equation does not hold true, so it is not the correct answer.
4) -3x - 8 = -29
Substituting -7: -3(-7) - 8 = 21 - 8 = 13. This equation does not hold true, so it is not the correct answer.
Therefore, the equation that has a solution of -7 is 5x + 11 = -24.
