Hello!
To solve this equation, you need to follow SADMEP. SADMEP is subtract, addition, division, multiplication, exponents, and parentheses (if you notice it is PEMDAS backwards) when solving algebraic equations. The goal is to get the variable by itself.
n - 3/5 = 2/5 (add 3/5 to both sides - the denominator of both fractions are equal)
n = 1
Therefore, the value of the variable n is equal to 1.
