Which of the following equations has a solution of -7? (1 point)
- x + 3 = - 4
O - 3x - 8 = - 29
5x + 11 = - 24
4x - 23 = 5
The equation that has a solution of -7 is:
- x + 3 = -4
Which of the following equations has a solution different from the rest?
- 1/7 * x - 3/4 = 1/4
O - 0.35x - 0.52 = 1.93
1/2 * x - 3 = 1/2
O 3/4 * x + 5 = - 1/4
The equation that has a solution different from the rest is the equation:
- 0.35x - 0.52 = 1.93
