Put the steps in order to solve the equation 3n+9+4n=2
1. Combine like terms on the left side of the equation: 3n + 4n = 7n
2. Simplify the equation further: 7n + 9 = 2
3. Subtract 9 from both sides of the equation: 7n = 2 - 9 = -7
4. Divide both sides of the equation by 7: n = -7/7 = -1
Therefore, the solution to the equation 3n + 9 + 4n = 2 is n = -1.
To solve the equation 3n + 9 + 4n = 2, follow these steps:
Step 1: Combine like terms on the left side of the equation. Here, we can combine 3n and 4n:
3n + 4n + 9 = 2
Step 2: Add or subtract the constants on both sides of the equation. Here, we subtract 9 from both sides:
7n + 9 - 9 = 2 - 9
Step 3: Simplify the equation.
7n = -7
Step 4: Isolate the variable by dividing both sides of the equation by the coefficient of n. Here, we divide both sides by 7:
7n/7 = -7/7
Step 5: Simplify further.
n = -1
Therefore, the solution to the equation 3n + 9 + 4n = 2 is n = -1.
