Solve the following equation
l+l+10=72
Solve for l
l + l + 10 = 72
Group the l terms on the left:
(1 + 1)l = 2l
Form modified equation
2l + 10 = + 72
Group constants
Group our constants 10 and 72.
subtract 10 from both sides
2l + 10 - 10 = 72 - 10
Cancel 10 on the left side:
2l = 62
Divide each side of the equation by 2
| 2l | |
| 2 |
| = |
| 62 |
| 2 |
l = 31
Final Answer
l = 31
