Question

What is the first step in solving the equation 3.5 n + 6.4 = 42.5?

Answer 1

n= 361/35

alternative forms:

n= 10 11/35 or n= 10.3142857

Explanation:

3.5n+6.4=42.5

move constant to the right

3.5n=42.5-6.4

subtract 42.5 to 6.4

3.5n=36.1

divide both sides by 3.5

----------------

n=361/35

----------------

Answer 2

I would add like terms, meaning subtract 6.4 from both sides.

3.5n = 36.1
