Answer:
X+y=25 and X-y=5. What is the value of X and y?
The answer to the question that is the value of X and y is 15 and 10.
Step by step explanation:
It is a type of linear equation in two variables.
X+y=25—equation 1
X-y=5—equation 2
Adding the equation 1 and 2
(You can also do subtraction and can find the value of y and then substitute it in equation 1 or 2 to get the value of X)
=>(X+y)+(X-y)=25+5
=>X+y+X-y=30
=>X+X=30
=>2X=30
=>X=30/2
=>X=15
The value of X is 15, and for the value of y, by using substitution method, we put the value of X in either first equation or second equation. So, I will put X in equation 1.
Putting the value of X in equation 1
=>X+y=25
=>15+y=25
=>y=25–15
=>y=10
You can also put X in equation 2 to get the answer but it will be same in both cases.
So finally the value of X is 15 and y is 10.
hope it helps you keep smiling :)
Answer:
x=35,y=55. because of in x and y are 15 is common diffrence. please mark me brainlist answer
