=7125-3375=3750

Answer 2

Câu 3:

a)(6-10)+150                  75.95-75.45

=(-4)+150                      =75.(95-45)

=146                              =75.50

                                      =3750

B)45-4x=37                    (3x-6).3=3^4

4x =45-37                      (3x-6)=3^4:3

4x =8                              (3x-6)=27

X=8:4                             3x =27+6

X=2                               3x =33

                                      x=33:3

                                      x=11
