Lesson Steps
| Step | Type | Explanation | Answer |
|---|---|---|---|
1 |
Problem |
Solve the equation: |
|
2 |
Step |
After Multiplication |
\$ (5x+55)/3 = (12x-6)/5 \$ |
3 |
Hint |
By Cross multiplication |
\$ (5x+55)\times5 = (12x-6)\times3 \$ |
4 |
Step |
After Multiplication |
25x + 275 = 36x - 18 |
5 |
Step |
Move Constant terms to right side and Variable terms to left side we get |
25x - 36x = - 275 - 18 |
6 |
Step |
Taking 'x' common |
(25-36) x = - 275 - 18 |
7 |
Step |
After subtraction we get |
-11 x = -293 |
8 |
Step |
Dividing with -11 on both sides |
\$ (\cancel(-11)x)/\cancel(-11) = (\cancel(-) 293) / (\cancel(-) 11) \$ |
9 |
Step |
After Cancellation |
\$ x = 293/11 \$ |
