You would take 2 and replace it for x in your other equation and solve.
Can't be done unless you have another equation with the same x and y. Then you would solve for simultaneous equations.
250x = 400000 then x log 250 = log 400000 so x = log 400000 / log 250 Natural logs could have been used instead of logs to base 10.

11 cubed equals 1331

No, it would be rounded to 400000.
3 to the power of 3 is the same as 3 cubed. To put it in an equation that would be 3x3x3 which equals 27.

You would do it it by oppisites. 3+2+4=9 which equals C.

What are we solving here for, Z, X, or Y?If solve for Z then the answer would be z = x + yIf solve for X then the answer would be z = z - yIf solve for Y than the answer would y = z - xHope this help.
