Which of the following equations has a solution of −8 ?(1 point)
Responses
1) 2x + 10 = -6
2) 3x - 4 = -20
3) 4x + 6 = -26
4) 5x - 2 = -42
To determine which equation has a solution of -8, we substitute -8 for x in each equation and check if the equation is true.
1) 2(-8) + 10 = -16 + 10 = -6 => not true
2) 3(-8) - 4 = -24 - 4 = -28 => not true
3) 4(-8) + 6 = -32 + 6 = -26 => true
4) 5(-8) - 2 = -40 -2 = -42 => true
Therefore, the equations that have a solution of -8 are equations 3) and 4).
