On​ average, a family of two adults and two children pays ​$97 per night for lodging and $105 a day for food while on vacation this year. If this increases by ​4% over the next​ year, find the total cost per day for lodging and meals for such a family after the increase.

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
