Question

Solve 5n – 7p + 3n = 25p for n.

Answer 1

Simplifying:

5n + -7p + 3n = 25p

Reorder the terms:

5n + 3n + -7p = 25p

Combine like terms: 5n + 3n = 8n

8n + -7p = 25p

Solving:

8n + -7p = 25p

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '7p' to each side of the equation.

8n + -7p + 7p = 25p + 7p

Combine like terms: -7p + 7p = 0

8n + 0 = 25p + 7p

8n = 25p + 7p

Combine like terms: 25p + 7p = 32p

8n = 32p

Divide each side by '8'.

n = 4p

Simplifying:

n = 4p

Hope this helps!

Answer 2

5n – 7p + 3n = 25p

Combine like terms

8n - 7p = 25p

Add (7p) to both sides

8n - 7p + 7p = 25p + 7p

Simplifying

8n = 32p

Divide both sides by 8

8n / 8 = 32p / 8

Simplifying

n = 4p
