Answer: (7,5) X=7 and Y=5
Explanation:
Add the two equations together to eliminate y from the system.
x-y=2 + x+y=12
= 2x = 14
Divide both sides by 2
x=7
Substitute the value found for x into one of the original equations to solve for y
(7)-y=2
Move all terms to one side to make it easier
-y=2-7
Subtract
y=5
Answer: Union of two sets.
Explanation: "An element is in the union of two sets if it is in the first set, the second set, or both. The symbol we use for the union is ∪ . The word that you will often see that indicates a union is "or".

Answer:
1.2
Step-by-step explanation:
15 ÷ 12.50 = 1.2
12.50(1.2)= 15
The y-value must be the numerator.
The correct way of solving this would be (7-10)/(3-5)=3/2
Actually I had learnt this but.....do u want a formula ?
