I want excel to solve for x in the following equation if possible

0.26 + x =0.22 notnsure if I'm writing it right nut Basically I'm running a finance goal and i need my cost to be 22 percent for the week. Monday it was 26 I need to know what percent Tuesday needs to be to get back to an average of 22 percent

I know the answer is 0.18 but can I get excel to give me that answer?

    From your description I guess that you want the average of 0,26 and x to be 0,22.

    One option:

    (0.26 + x) / 2 = 0.22

    0.26 + x = 2*0.22

    x = 2*0.22 - 0.26

    So the formula =2*0.22-0.26 will return the number you want.

    Another option:

    In A1, enter 0,26

    Leave B1 empty

    In C1, enter the formula =AVERAGE(A1:B1)

    On the Data tab of the ribbon, in the Forecast group, select What-If Analysis > Goal Seek...

    Enter C1 in the 'Set cell' box.

    Enter 0.22 in the 'To value' box.

    Enter B1 in the 'By changing cell' box.

    Click OK. After a short interval, Excel should find a solution:

    As you seem B1 now contains 0,18.
