Question

Solve for w.

10 + 9w = 5w − 10

w =

Answer 1

10 + 9w = 5w -10


Move variable to the left-hand side and change its sign

10 + 9w 5w - 10


Move constant to the right-hand side and change its sign

9w -5w = -10 -10


Collect like terms

4w = -10 -10


Calculate the difference

4w = -20


Divide both sides of the equation by 4

W = -5

And the answer is

W = -5

Answer 2

w=-5

Explanation:

Let's rewrite the equation.

10+9w=4w-10.

Next, we want variables on one side and constants on the other.

9w-4w=-10-10

Add like terms.

4w=-20

Now divide.

w=-5

Done!
