Number of nickels plus number of dimes equals total number of coins
so
n + d = 40
then they tell us that "there are seven times as many dimes as there are nickels"
this translates to
d = 7n
we then plug that into our first equation
and get
n + 7n = 40
then we solve for n
add like terms
8n = 40
then divide both sides by 8
n = 40/8 = 5
therefore Jimmy has 5 nickels
X - tickets
----------------------------------
167x + 19x + 16 = 1132
186x + 16 = 1132
186x = 1132 - 16
186x = 1116
x = 1116 : 186
x = 6 tickets (answer).
B= -42 C= -38
So the difference going up to positive is 4 and the difference going down in negative is -4.
