Use gauss-jordan row reduction to solve the given system of equations. hint [see examples 1-6.] (if there is no solution, enter no solution. if the system is dependent, express your answer in terms of x, where
y = y(
5x − 3y = 7
10x − 6y = 14

  y = 5/3x -7/3

Step-by-step explanation:

Subtracting twice the first equation from the second gives a row of zeros, indicating the system is dependent. Solving the first equation for y gives:

  5x -7 = 3y

  y = 5/3x -7/3 . . . . y in terms of x

You could write the solution as ...

  (x, y) = (x, 5/3x -7/3)

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490
