Tyler has 4 times as many coins as Oliver. If Oliver had 27 more coins,
the two boys would have exactly the same amount. How many coins does Tyler have?
~~~~~~~~~~~~~~~~~~
x = # of coins Oliver has;
4x = # of coins Tyles has.
Equation
x + 27 = 4x.
Solution
27 = 4x - x
27 = 3x
x = 27/3 = 9.
ANSWER. Tyler has 4*9 = 36 coins.
Solved.
