Plz help me with this problem! (I would put this for 25-50 points but then ppl don't give real answers they just say random things.) What is N? Use the seesaw principle.

5 feet

Step-by-step explanation:

38xN=10(4)+15(10)

38N=40+150

38N=190

N=5

Hey!

Alright, let's take a look at this problem.
The first step would be to rearrange the equation. To do that we will group the like elements.

Original Equation :
7x - 8 - 3x - 4

New Equation {Changed by Grouping Like Elements} :
7x - 3x - 4 - 8

Next, we'll add both the 7x and 3x since they both contain variables.

Old Equation :
7x - 3x - 4 - 8

New Equation {Changed by Adding Similar Elements} :
4x - 4 - 8

Again, we'll add the other similar elements in the equation.

Old Equation :
4x - 4 - 8

New Equation {Changed by Adding Similar Elements} :
4x - 12

Our equation can no longer be simplified any farther, so we have our final answer.

The equation 7x - 8 - 3x - 4 simplified is  4x - 12.

Hope this helps!
