Zachary and Dovante deliver packages. Dovante delivers 9 less than 4 times the number of packages Zachary delivers in one day. Dovante delivers no more than 11 packages in one day. Write an inequality to find the number of packages Zachary delivers in one day.

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

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x

8.3 and the 3 is repeating

hope this .
