The answer to this would be x-(x+14)
Here's an explanation:
Let x represent the unknown number. The problem says that x has been decreased by the sum of x and 14. So, to put this in a form of an equation, it would be x-(x+14), since you have to do the addition first before you can subtract the two number since you don't know what x is. This equation is equal to -14 no matter what x is.

Answer:
I think it's 7=2x+3
Step-by-step explanation:
The diagram shows a balanced set of 2 sides, meaning that both sides equal each other. I assume you don't know what x is, so the simplest you can do to combine all three parts of the left side of the diagram is 2x+3, which of course equals 7, the right side.
I'm not the best at explaining, but I hope that helps.
Two supplementary angles when added together need to equal 180 degrees.
Let the first angle = X
The second angle would then be X - 152
Add them together to equal 180:
X + X - 152 = 180
Simplify:
2X -152 = 180
Add 152 to each side:
2X = 332
Divide both sides by 2:
X = 332 / 2
X = 166
The first angle = X = 166 degrees.
The second angle = X - 152 = 166 - 152 = 14 degrees.
The angles are 166 and 14
