Step 1: Combine like terms on the left side of the equation. So, 3n + 4n simplifies to 7n. Therefore, the simplified equation is 7n + 9 = 2.
Step 2: Subtract 9 from both sides of the equation to isolate the variable term. This gives us 7n = -7.
Step 3: Divide both sides of the equation by 7 to solve for n. This yields n = -1.
Put the steps in order to solve the equation: 3n+9+4n=2

3i+2i−4=18i
3(2i−7)=6i−21
2i+3=2i−5
3i+2i-4=18i --> Solution: i = -1
3(2i-7)=6i-21 --> Solution: i = 0
2i+3=2i-5 --> Solution: There is no solution.
3(2i-7)=6i-21 --> Solution: i = 0
2i+3=2i-5 --> Solution: There is no solution.
