Solving a linear equation
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.
