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

T : trucks

c: cars

t + 4 + 2t = 127

3t = 123

t = 123 / 3

t = 41

c = 127 - 41 = 86

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
