**Question**

What is 5n - 2n + 12 + 20 = 5

**Answer**

**STEP 1: ** Here, we need to find the value of n. We note that the terms 5n and 2n are

like terms. So, we first subtract 2n from 5n.

**STEP 2: ** Now, we add the like terms 12 and 20 to further simplify the expression.

**STEP 3: ** Next we have to isolate the variable term 3n so that it becomes easy to evaluate n. For this, we subtract 32 from both sides of the equation.

**STEP 4: ** To get the value of n, the only step left now is to isolate n in the equation. We divide both the sides by 3 to evaluate n.

The value of n is –9.
