which ordered pair is the solution of this equation.

Question

2x-2y= 10.

 

(   ,0,)

 

Please provide an explanation for future problems 

Answer 1

you can divide 2x - 2y= 10 by 2 to make it simple (divide both sides by 2). It will give you x - y = 5. However, I disagree with Jim on the rest. Yes, there are a lot of numbers which difference will give you 5 but you are provided with a clue. ( ,0) - a point. Any point is designated by (x, y). So they tell you that your y=0. Plug it back into the equation: x - 0 = 5 x= 5. Therefore, your point is (5,0).

Answer 2

Hi,

 

       You only provided one equation which can be written as x-y=5 so any two numbers that differ by 5 will be a solution. for example (0,-5) (1,-4) (10,5) are all examples of ordered pairs that are solutions.
