Solve the following equation
1200+0.2n=850+0.3n
Solve for n
1200 + 0.2n = 850 + 0.3n
Group variables
Group our variables 0.2n and 0.3n
subtract 0.3n from both sides
0.2n + 1200 - 0.3n = 0.3n + 850 - 0.3n
Cancel 0.3n on the right side:
-0.1n + 1200 = 850
Divide each side by 1200
| 1200n | |
| 1200 |
| = |
| 0.2 |
| 1200 |
Group constants
Group our constants 1200 and 850.
subtract 1200 from both sides
-0.1n + 1200 - 1200 = 850 - 1200
Cancel 1200 on the left side:
-0.1n = -350
Divide each side of the equation by -0.1
| -0.1n | |
| -0.1 |
| = |
| -350 |
| -0.1 |
n = 3500
Final Answer
n = 3500
