Answer 1

7.


a = (9000-75:5-8905):4
a = (9000-15-8905):4
a = (8986-8905):4
a = 80:4
a = 20.



b = 76×8×(2987-2986)-575
b = 608×1-575
b = 608-575
b = 33.


c = 3000-(48×7-85:5)-2669
c = 3000-(336-17)-2669
c = 3000-319-2669
c = 2681-2669
c = 12.


d = 76:4+45×4+9:9-164
d = 19+180+1-164
d = 199+1-164
d = 200-164
d = 36.



4×a-b:3+5×c+d:6 =
4×20-33:3+5×12+36:6 =
80-11+60+6 =
69+66 = 135.






I hope I helped you :)
