Answer:
9
Step-by-step explanation: 36 divided by 4 is 9.
Answer:
y = 2M - x
Step-by-step explanation:
M = (x + y)/2 Multiply both sides by 2
2M = x + y Subtract x from each side
y = 2M - x
In a trapazoid the diagonals are the same so therefore the two equations equal echother
3x+7=5x-11 solve for x by combining like terms
18=2x then divide to unto multiplication
9=x
9 is the value of x
I hope I've helped!
2x = 15 + x
First, our goal is to get 'x' to equal something by itself. To do so, we will have to do everything on one side. Let's subtract 'x' from each sides.

Second, our next step is to subtract '2x - x'. Since 'x' is basically considered (1), it will equal 'x'.

Answer:
X=21
