Answer:
n=S+360÷180
Step-by-step explanation:
S=(n-2) 180
S= 180n-180*2
S=180n-360
180n-360=S
180n =S+360
180n÷180=S+360÷180
n=S+360÷180

Because there are 4 people and all bought the same things you multiple 4(4+1+2)=4x7=28 So the total cost is $28
Answer:
x = 5 , y = 2
Step-by-step explanation:
5x + 2y = 29 ....................(1)
x + 4y = 13 Multiply this equation by -5:-
-5x - 20y = -65.................(2)
Add equations (1) and (2):-
-18y = -36
y = 2
Substitute for y in equation (1):-
5x + 2(2) = 29
5x = 25
x = 5
Check the results in the second equation:-
x + 4y = 13
5 + 4(2) = 13 - It checks out.
