Adam had 42 more toy cars than Beckham. After Adam gave 118 toy cars to Beckham, Beckham had thrice as many toy cars as Adam. How many toy cars did Adam have in the end?

a = b + 42 given re written as a-42 = b

then

(a-118) * 3 = (b+118) sub in the red equation for b

3a - 354 = ( a-42 + 118 )

a = 215 originally ...... then he gives away 118 to have 97 in the end.
