Question

What is craft of Y to y 2 2 into x 2 Y - 10 x y 2

Answer 1

Step-by-step explanation:

To calculate the value of X and Y from following equations

X + Y = 10…. Eq..1

X - Y = 2

Or X = 2 + Y….Eq..2

Now putting the value of X from Eq..2 to Eq..1

X + Y = 10

(2 + Y) + Y = 10

2 + Y + Y = 10

2 + 2Y = 10

2Y = 10 - 2

2Y = 8

Y = 8/2

Y = 4

Now putting the value of Y in Eq..1

X + Y = 10

X + 4 = 10

X = 10 - 4

X = 6

Answer the value of X is 6 and the value of Y is 4

Now check correctness of answer

X + Y = 10

6 + 4 =10

10=10

Means answer is correct.

If x+y+2=x+y, what is x?

If 10x+y=8,x-y=2, then what is x and y?
