Question

Solve for w. 5w + 9z = 2z + 3w w = z w = z w = –2z w = –7z

Answer 1

5w + 9z = 2z + 3w

Subtract 2Z from each side:

5w + 7z = 3w

Subtract 5w from each side:

7z = -2w

Divide both sides by -2:

w = 7z / -2

Answer 2

We have been given an equation  and we are asked to find value of w from our given equation.

$5w+9z=2z+3w$

First of all we will subtract 3w from both sides of our equation.

$5w-3w+9z=2z+3w-3w$

$5w-3w+9z=2z$

Now let us subtract 9z from both sides of our equation.

$5w-3w+9z-9z=2z-9z$  

$5w-3w=2z-9z$

$(5-3)w=(2-9)z$

$2w=-7z$

Now let us divide both sides of our equation by 2.

$\frac{2w}{2}= \frac{-7z}{2}$

Upon cancelling 2 from left side of our equation we will get,

$w=\frac{-7}{2} z$

Therefore, we can see that $w=\frac{-7z}{2}$.
