Question 33513
2/7b - 9 = 2 
2/7b = 2+9 ( when -ve sign goes to other side of equation it cnages to +ve)
2/7b = 11
2 = 11*7b
b = 2/77


3(22V - 1) = 162 
(22v - 1) = 162/3 = 54
22v - 1 = 54
22v = 54 +1 (when -ve sign goes to other side of equation it cnages to +ve)
22v = 55
v = 55/22 = 5/2

I didnt understand another bracket ending after 2 when there is no beginning bracket. so iam assuming the problem to be 
-6 (m+2)+ 2 +4 = 36 
-6(m+2) +6 = 36
-6(m+2)=36-6(when +ve sign goes to other side of the equation it changes to 
-ve)
-6(m+2) = 30
-(m+2)= 30/6 = 5
-m - 2 = 5
-m = 5+2 = 7
m = -7


5 - 40x = 125 
-40x = 125 -5
-40x = 120
-x = 120/40
-x = 3
x = -3
