Question

there are total of 127 cars and trucks on a lot if there are four more than twice the number of Trucks Than Cars how many cars and trucks are on the lot

Answer 1

C=number of cars
t=number of trucks
c+t=127=total

if there are 4 more than (+4) 2wice the number of trucks (2 times t or 2t) than are cars (= c) find c and t
4+2t=c and c+t=127
subsitute 4+2t for c
4+2t+t=127
4+3t=127
subtract 4
3t=123
divide 3
t=41
subsitute
t+c=127
41+c=127
subtract 41
c=86

86 cars
41 truckes

Answer 2

T : trucks
c: cars

t + 4 + 2t = 127
3t = 123
t = 123 / 3
t = 41
c = 127 - 41 = 86
