To find the equation with a solution of -7, we can substitute -7 into each equation and see which one simplifies to a true statement.
1) For 5x+11=-24, if we substitute -7 for x, we get 5(-7)+11=-24, which simplifies to -34 ≠ -24. Therefore, this equation does not have a solution of -7.
2) For -x+3=-4, if we substitute -7 for x, we get -(-7)+3=-4, which simplifies to 10 ≠ -4. Therefore, this equation does not have a solution of -7.
3) For 4x-23=5, if we substitute -7 for x, we get 4(-7)-23=5, which simplifies to -51 ≠ 5. Therefore, this equation does not have a solution of -7.
4) For -3x-8=-29, if we substitute -7 for x, we get -3(-7)-8=-29, which simplifies to 13 = -29. Therefore, this equation does not have a solution of -7.
None of the given equations have a solution of -7.
Which of the following equations has a solution of −7 ?(1 point) Responses 5x+11=−24 5 x plus 11 equals negative 24 −x+3=−4 negative x plus 3 equals negative 4 4x−23=5 4 x minus 23 equals 5 −3x−8=−29
