By looking at what we have we can see that we have a relation between R & S and T & S.
Solve the 2nd and 3rd equations for R and T.
2R = S
R = S/2
3T = S

2x + 4 = 36
Subtract 4 from each side
2x + 4 - 4 = 36 - 4
2x = 32
Divide both sides by 2

Your goal is to get the x on one side and the answer on the other side.
16x + 10 - 32 = 35 - 10 - 5
First, combine like terms.{10 - 32 = -22} & {35 - 10 - 5 = 20}
16x - 22 = 20

It depends on how hungry they are.
Area formula is A=LW
Perimeter formula is P = 2L + 2W
P = 18
A = 18
Using the area formula
18 = LW
solve for L
L = 18/W
Substitute the 18/W for the L in the Perimeter formula
18 = 2(18/W) + 2W
18 = 36/W + 2W
36/W + 2W - … Read more
First put them in order

Pick the number in the middle
In this case there is not one in the middle, there are two so you have to average the two.
(34 + 38)/2 = 36
