Sam swam x fewer laps than his friend Kristen, who swam 3 laps. Which expression represents the number of laps Sam swam?

A) x/3

B) 3-x

C) 3x

D) x-3

Im pretty sure 3x it is

i need a picure

step-by-step explanation:

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
