How To Solve a Problem With Variables on Both Sides

In order to solve h = p/n, we must get p by itself.

Therefore, you can multiply both sides by n.

hn = p * n
- -
n 1

Since you have an n in the numerator and denominator, they cancel and you are left with p on the right hand side.

Therefore, hn = p

Hope this helps!

How to Solve a Problem with Variables on Both Sides
by: Karin

Hi Cheyanne,

When solving an equation with variables on both sides, the most important thing to remember is that you want to get all of the variables on one side of the equation and all of the constants on the other side. You can do this by adding and subtracting the terms. Take a look...

25u + 74 = 23u + 92

Step 1: Get all of the variables on the left hand side by subtracting 23u from both sides.

25u -23u +74 = 23u - 23u + 92

Now Simplify:

2u + 74 = 92

Step 2: Now the variables are on the left, and you must move the constant 74, to the right by subtracting 74 from both sides.

2u + 74 - 74 = 92 - 74

Simplify:

2u = 18

Step 3: Get u by itself by dividing by 2 on both sides.

2u/2 = 18/2

Simplify:

u = 9

Your answer is u = 9.

Best of luck,
