Question

(4x + 5): 3-121:11=4

Answer 1

(4x + 5) : 3 - 121 : 11 = 4

        (4x + 5) : 3 - 11 = 4

              (4x + 5) : 3 = 4 + 11

              (4x + 5) : 3 = 15

                     4x + 5 = 15 . 3

                     4x + 5 = 45

                           4x = 45 - 5

                            4x = 40

                              x = 40 : 4

                              x = 10

Vậy x = 10

Answer 2

(4x+5):3-121:11=4

=>(4x+5):3-11=4

=>(4x+5):3=4+11=15

=>4x+5=15.3=45

=>4x=45-5=40

=>x=40:4=10

Vậy x=10
