Answer:
-3.20
Step-by-step explanation:
by using BODMAS
consider bracket 1= [1/7)-2*(1/7)3]
on solving we get.
[1/7)-2*(1/7)3]
= [1/7-(2/7)*3]
= [1/7-6/7]
= -5/7
now multiplying with 2
= -5/7*2 = -10/7
multiplying with 1/7 we get
= -10/7* 1/7
= -10/49
substracting with 3 we get.
= -10/49 -3
= -10 -147/49
= -157/49
= -3 10/49
= -3.20
