Number of coins with Ted #=22#

Number of coins with Mac #=52#

Let us assume the number of coins with Ted #=x#

Then Number of coins with Mac #=2x+8#

Total Number of coins #=74#

Then -

#x+2x+8=74#
#3x+8=74#
#3x=74-8=66#
#x=cancel66/cancel3=22#

Number of coins with Ted #=22#

Number of coins with Mac #=2(22)+8=44+8=52#
