Question

4(m-1)+3m=3(4×-5)-1
Me ajudem

Answer 1

4(m-1)+3m=3(4x-5)-1

4m - 4 + 3m = 12x - 15 -1

7m -4 = 12x - 16

7m -4 - 12x + 16 = 0

7m -12x + 12

Answer 2

                    4(m-1)+3m = 3(4×-5)-1
                    4m -4 +3m = 12x - 15 -1
                           7m - 4 =  12x - 16
                           7m - 12x = -16 + 4
                           7m - 12x = -12
                           12x = 7m + 12     
                               x = 7m/12 + 12/12
                               x = 7m/12 + 1
