The correct option is A, which is {(5/7, 12/7)}.
<h2>Given to us,</h2>
equation 1, 5x + 2y = 7,
equation 2, y = x+1
To solve the question, as given in equation 2 the value of y which is equal to x+1, Substitute the value of y in equation 1,

<h3>substituting,</h3>

Now, we have the value of x, substitute the value in equation 2, to get y,

Taking LCM,

Hence, the correct option is A, which is {(5/7, 12/7)}.

2x multiplies to all numbers:
2x x 8x3 = 16x4
2x x 6x2 = 12x3
2x x -10x = -20x2
Answer: 16x4 + 12x³ - 20x²
Hope this helps :)
Image below, rotation for point (5,-2) gives you (2,5).
To find the mean all you have to do is add all the numbers...
you should get -30
and divide by a number of numbers, there are 6
so -30/6 is -5
