Anyone now how to do this..

1) x = 4; y = -2

Explanation:

1)

2x - y = 10;

x + y = 2

In order to do the elimination process, you must find two variables (either the x values or the y values) that are the exact opposites of each other. In this case, it isn't too hard since we have 1y and -1y, so now we eliminate them.

2x = 10;

x = 2

Now we add up both sides, so that it turns into 1 equation.

3x = 12;

Now we solve for one x

x = 4;

Now, we use this value and input it in both of the original equations to find and check for the other value, y.

2(4) - y = 10

8 - y = 10

-y/-1 = 2/-1

y = -2;

(4) + (-2) = 2

Does that help?

i think it is b hope this

after lydia compare her check register to her bank statement, and the ending balances do not seem to match. then, she must make a bank reconciliation by putting the data all together.

to do this, she need to determine the bank ending balance. after, add the deposits in transit then deduct the outstanding checks. moreover, if the actual checkbook balance does not equal this number, check again for transporting errors by subtracting the balances and add the difference to nine. sometimes, a mathematical error can happen but a bank reconciliation is a great tool to resolve the discrepancies.
