If 3(n+8)=36 what is the value of n

Thus, n = 4 is the solution.

Step-by-step explanation:

1.  perform the indicated multiplication, obtaining 3n + 24 = 36

2.  Subtract 24 from both sides:   3n = 12

3.  Solve this result for n:  n = 12/3.  Thus, n = 4 is the solution.

4 is the value of n

Step-by-step explanation:

First you want to get the n by itself, which means dividing the 3...

36 / 3 = 12 -- So your equation looks like this n+8=12, subtract the 8 to get 4

12-8 = 4, once you plug the 4 back into the normal equation you get 36

3(4+8)=36

step-by-step explanation:

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
