Step 1: Combine like terms by adding 3n and 4n: 3n + 4n = 7n
Step 2: Simplify the equation by subtracting 9 from both sides: 7n + 9 - 9 = 2 - 9
7n = -7
Step 3: Solve for n by dividing both sides by 7: 7n/7 = -7/7
n = -1
Step 1: Simplify the equation by combining like terms on the left side: 3n + 4n = 7n.
Step 2: Rewrite the equation with the simplified term: 7n + 9 = 2.
Step 3: Solve for n by isolating the variable. Subtract 9 from both sides of the equation: 7n = -7.
Step 4: Divide both sides of the equation by 7: n = -1.
Reasoning: To solve the equation, we need to simplify the left side by combining like terms. Then, we can isolate the variable n by performing inverse operations. First, we subtract 9 from both sides to isolate the variable term. Finally, we divide both sides by 7 to solve for n.
