Solve the following equation
0.2p+6.8=0.3p+4.7
Solve for p
0.2p + 6.8 = 0.3p + 4.7
Group variables
Group our variables 0.2p and 0.3p
subtract 0.3p from both sides
0.2p + 6.8 - 0.3p = 0.3p + 4.7 - 0.3p
Cancel 0.3p on the right side:
-0.1p + 6.8 = 4.7
Divide each side by 0.2
| 0.2p | |
| 0.2 |
| = |
| 6.8 |
| 0.2 |
Group constants
Group our constants 6.8 and 4.7.
subtract 6.8 from both sides
-0.1p + 6.8 - 6.8 = 4.7 - 6.8
Cancel 6.8 on the left side:
-0.1p = -2.1
Divide each side of the equation by -0.1
| -0.1p | |
| -0.1 |
| = |
| -2.1 |
| -0.1 |
p = 21
Final Answer
p = 21
