Which choice describes whether x = 19 is the solution of the equation 42 = 3x - 15? CLEAR CHECK x = 19 is not the solution because 3 • 19 - 15 = 3 • 4 = 12, not 42. x = 19 is the solution because 3 • 19 - 15 = 3 • 4 = 12. x = 19 is the solution because 3 • 19 - 15 = 57 - 15 = 42. x = 19 is not the solution because 3 • 19 - 15 = 57 - 15 = 42.

Donavan Burch · Answer 1

42 = 3x - 15 Since you know x = 19, you can plug in 19 for "x" in the equation

42 = 3 (19) - 15

42 = 57 - 15

42 = 42 This is the solution

x = 19 is the solution because 3 • 19 - 15 = 57 - 15 = 42. (3rd choice)
