2. at each scooter's top speed, brand a scooter goes 2 miles per hour faster than brand b. if after traveling at its top
speed for 3 hours, brand a scooter traveled 40.2 miles, at what rate did brand b scooter travel if it traveled the
same distance as brand a? write an equation to determine the solution and then write an equivalent equation
using only integers.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

step-by-step explanation:

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
