We will need to eliminate the value of x to solve for y. If you want to solve for x first, do not eliminate it. Eliminate the 'y' variable. Once either variable is eliminated, it will be very easy to solve. Please check out my solution to learn more.
My solution:
=> 3x + 7y = 68
3x - y = 4
=> 3x + 7y = 68
-3x + y = -4
=> 8y = 64
=> y = 8
=> 3x + 7y = 68
=> 3x + 7(8) = 68
=> 3x + 56 = 68
=> 3x = 12
=> x = 4
Hence, the correct step is "subtract to eliminate x".
how to do it! 11 x 28 x 12= volume of storage bin divide volume of storage bin by the volume of 1 bushel and round to the nearest tenth. <span>multiply .021722 by how many bushels can fit in the bin.</span>
