Solve 12n+7p - 6n = 25p for n.

n = 3p

Step-by-step explanation:

12n + 7p - 6n = 25p; solve for n

First we will add like terms in the left side

12n - 6n + 7p = 25p

6n + 7p = 25p

Subtract 7p to both sides

6n + 7p - 7p = 25p - 7p

6n = 18p

Now divide 6 from both sides

6n/6 = 18p/6

n = 3p

Create a number line with small lines

Example:

<-| ---1/32/3|->

It's also on the left hand side of the number line.

Left of the number 0.
