Step 1: Combine like terms on the left side of the equation by adding the coefficients of n. 3n + 4n = 7n.
Step 2: Rewrite the equation with the simplified expression. 7n + 9 = 2.
Step 3: Move the constant term to the right side of the equation by subtracting 9 from both sides. 7n = 2 - 9.
Step 4: Simplify the right side of the equation. 7n = -7.
Step 5: Solve for n by dividing both sides of the equation by 7. n = -7/7 = -1.
Step 6: The solution to the equation is n = -1.
Step 1: Combine like terms by adding the terms with the variable n: 3n + 4n = 7n.
Step 2: Rewrite the equation with the combined terms: 7n + 9 = 2.
Step 3: Subtract 9 from both sides of the equation to isolate the variable term: 7n + 9 - 9 = 2 - 9.
Step 4: Simplify both sides: 7n = -7.
Step 5: Divide both sides by 7 to solve for n: 7n / 7 = -7 / 7.
Step 6: Simplify: n = -1.
Therefore, the steps in order to solve the equation 3n + 9 + 4n = 2 are:
1. Combine like terms: 3n + 4n = 7n
2. Rewrite the equation: 7n + 9 = 2
3. Subtract 9 from both sides: 7n + 9 - 9 = 2 - 9
4. Simplify: 7n = -7
5. Divide both sides by 7: 7n / 7 = -7 / 7
6. Simplify: n = -1.
