An architect is designing a house. She wants the bedroom to have the dimensions of 9 ft by 4 ft by 7 ft. The architect doubles one dimension to create the den. Does that mean the den will have double the volume of the bedroom? Does doubling one dimension mean the den will have double the volume of the bedroom? Why or why not?
please answer I need this by 9:00

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

i think the answer is a p = 78
