Jubal wrote the four equations below. He examined them, without solving them, to determine which equation has no solution. 7 x + 1 = 7 x+ 1. 3 x + 2 = 3 x - 2. 4 x + 1 = 3 x + 8. -2 x - 1 = -2 x - 1. Which of Jubal’s equations has no solution? 7 x + 1 = 7x +1 3 x + 2 = 3 x - 2 4 x + 1 = 3 x + 8 -2 x - 1 = -2 x - 1
