does anyone wanna try this really hard algebra problem??? please?

Question

*= squared (because i cant do the small 2 on the keyboard)

xz*+ xw* =xy* + 5 (solve for x)

Answer 1

xz^2+xw^2=xy^2+5
xz^2+xw^2-xy^2=5
x(z^2+w^2-y^2)=5
x=5/(z^2+w^2-y^2)

Too easy!

Answer 2

The key to solving for one variable is isolating it. Recall the addition quality of equality..

if a = b then a - 5 = b - 5

well you have this xz^2 + xw^2 for an 'a' and a xy^2 + 5 for a 'b', right? then it stands to reason that we can subrtract that xy^2 term and it'd end up on the other side.

xz^2 + xw^2 = xy^2 + 5
is now
xz^2 + xw^2 - xy^2 = 5

Now let's use the distributive of numbers to get that x out of each of those terms on the left side.

The distributive property goes like this

a*c + b*c = c*(a+b)

This means that since there's an x in each term, we can just weed it on out of there and put parentheses around the whole group. Sorta like herding in the cattle!

x * (z^2 + w^2 - y^2) = 5

That big boy doesn't look so bad now, does it??

Now all we gotta do is make the x and the 5 switch places.

If we divide by x on both sides, we'll end up with
(z^2 + w^2 - y^2) = 5 / x
and then the inverse is
1 / (z^2 + w^2 - y^2) = x / 5
so multiply by 5 and you get

x = 5 / (z^2 + w^2 - y^2)

Answer 3

Solving for x

xz² + xw² = xy² + 5

xz² + xw² - xy² = xy² + 5 - xy²

Subtracting - xy² from both sides of the equation

x(z² + w² - y²) = 5

removing the common factor x from the equation

x(z² + w² - y²)/ (z² + w² -y²) = 5/(z² + w² - y²)

Dividing (z² + w² - y²) from both sides of the equation

x = 5/(z² + w² - y²)

Answer 4

xz² + xw² = xy² + 5
xz² + xw² – xy² = 5
x (z² + w² – y²) = 5

x = 5 ÷ (z² + w² – y²)

Answer 5

LMAO..I looked at the question...then said...5..I may be on the right track.
Purely by accident, unless I am some kind of mathamatical idiot sivante.
That is as opposed to just being a garden variety idiot.
Shine on

Answer 6

if you don't understand Dan's answer, ^2 means squared. When typing on the computer use the carrot (is that right?) sign ^ followed by the power.

Answer 7

(x*y)+z*=w*+5
x*=y+z+w+5
x=4

this is an advanced finite mathematics formula which significantly simplifes the problem ..


now try to use this as a hlepfull way to solve your problem effectively

Answer 8

I hope you at least worked a little on this problem yourself before asking everyone else to do your homework for you...

Answer 9

x(z^2+w^2-y^2)=5
x=5/(z^2+w^2-y^2)

Answer 10

x(z*+w*-y*)=5
x=5/(z*+w*-y*)
