Lesson Steps
Step | Type | Explanation | Answer |
---|---|---|---|
1 |
Problem |
Solve the equation |
|
2 |
Formula: |
By using formula |
\$| x |\$ = a |
3 |
Hint |
By removing mod we get (+) (or) (-) |
\$x = a (or) x = - a\$ |
4 |
Step |
Here 'a' is \$-4/6\$ |
\$ -x = -4/6 (or) -x = -(-4/6)\$ |
5 |
Step |
After multiplication we get |
\$ -x= - 4/6 (or) -x = 4/6 \$ |
6 |
Step |
Multiplying "-" on both sides we get |
\$-(-x) = -(-4/6) (or) -(-x) = - 4/6\$ |
7 |
Step |
After multiplication we get |
\$ x = \cancel4^2/\cancel6^3(or) x = - \cancel4^2/\cancel6^3 \$ |
8 |
Step |
After cancellation we get |
\$ x = 2/3(or) x = -2/3 \$ |
