Answer:


a) \: \: (3x + 2)/(4) = 5 \\ 3x + 2 = 5 * 4 \\ 3x + 2 = 20 \\ 3x = 20 - 2 \\ 3x = 18 \\ x = (18)/(3) \\ x = 6 \\ \\ b) \: (2x - 7)/(5) = 6 \\ 2x - 7 = 6 * 5 \\ 2x - 7 = 30 \\ 2x =30 + 7 \\ 2x = 37 \\ x = (37)/(2) \\ x = 18.5 \\ \\ c) \: (4x - 3)/(2) = - 4 \\ 4x - 3 = - 4 * 2 \\ 4x - 3 = - 8 \\ 4x = - 8 + 3 \\ 4x = - 5 \\ x = ( - 5)/(4) \\ x = - 1.25 \\ \\ d) \: \: (5x + 6)/(4) = - 6 \\ 5x + 6 = - 6 *4 \\ 5x + 6 = - 24 \\ 5x = - 24 + 6 \\ 5x = - 18 \\ x = ( - 18)/(5) \\ x = 3.6 \\ \\ e) \: (3x + 1)/( - 5) = 10 \\ 3x + 1 = 10 * - 5 \\ 3x + 1 = - 50 \\ 3x = - 50 - 1 \\ 3x = - 51 \\ x = ( - 51)/(3) \\ x = 71 \\ \\ f) \: (6x - 11)/( - 4) = - 1 \\ 6x - 11 = - 1 * - 4 \\ 6x - 11 = - 4 \\ 6x = - 4 + 11 \\ 6x = 7 \\ x = (7)/(6) \\ x = 1.16
