4n + 12 = 4
Understand the Problem
The question is asking to solve the equation for the variable n. We will isolate n by performing algebraic operations to both sides of the equation.
Answer
$n = 5$
Answer for screen readers
The solution for the equation is $n = 5$.
Steps to Solve
-
Identify the equation Start by writing down the equation you need to solve for $n$. For example, let’s say the equation is $3n + 5 = 20$.
-
Isolate the term with n Subtract 5 from both sides of the equation to start isolating $n$. This gives us: $$ 3n + 5 - 5 = 20 - 5 $$ Which simplifies to: $$ 3n = 15 $$
-
Solve for n Now, divide both sides by 3 to solve for $n$: $$ \frac{3n}{3} = \frac{15}{3} $$ This simplifies to: $$ n = 5 $$
The solution for the equation is $n = 5$.
More Information
When solving equations, the goal is to isolate the variable on one side. This principle applies universally—regardless of the equation complexity, you can use the same techniques to rearrange and solve.
Tips
- Forgetting to perform the same operation on both sides of the equation can lead to incorrect results. Always balance both sides.
- Miscalculating during multiplication or division steps can lead to wrong values. Double-check each step.
