Sarah and Kayla both solved the problem below. Who solved it correctly? Identify the mistake for the person who solved it incorrectly. Sarah 5x-15-3x = 10-(-3x+20) 2x 15 = 10 + 3x - 20 2x-15-10 + 3x - 3x -3x -1x 15-10 + 15 +15 - 1x = 5 x = -5 Kayla 5x-15-3x = 10- (-3x+20) 2x 15 = 10 + 3x - 20 2x-1510 + 3x +3x 5x - 15 = -10 +15 +15 5x = 5 x = 1 + 3x
