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

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

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

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

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

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

Therefore, we can see that .

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
