To find the equation that has a solution of -7, we need to substitute -7 for x and see which equation holds true.
For the first equation:
5x + 11 = -24,
Substituting -7 for x, we get:
5(-7) + 11 = -24,
-35 + 11 = -24,
-24 = -24.
This equation holds true when x = -7.
Similarly, substituting -7 for x in the other equations:
-3x - 8 = -29,
-3(-7) - 8 = -29,
21 - 8 = -29,
13 = -29.
This equation does not hold true when x = -7.
4x - 23 = 5,
4(-7) - 23 = 5,
-28 - 23 = 5,
-51 = 5.
This equation does not hold true when x = -7.
-x + 3 = -4,
-(-7) + 3 = -4,
7 + 3 = -4,
10 = -4.
This equation does not hold true when x = -7.
Therefore, the only equation that has a solution of -7 is 5x + 11 = -24.
Which of the following equations has a solution of −7?(1 point)
5x+11=−24 5 x plus 11 equals negative 24
−3x−8=−29 negative 3 x minus 8 equals negative 29
4x−23=5 4 x minus 23 equals 5
−x+3=−4
