|---|---|---|---|
1 |
Problem |
Calculate the equation |
|
2 |
Step |
Adding - 1 on both sides we get |
\$ 8| x + 6 | + \cancel1 - \cancel1 = 6 - 1 \$ |
3 |
Step |
After cancellation we get |
\$ 8| x + 6 | = 5 \$ |
4 |
Step |
Dividing on both sides by 8 we get |
\$ \cancel8/\cancel8| x + 6 | = 5/8 \$ |
5 |
Step |
After cancellation we get |
\$ | x + 6 | = 5/8 \$ |
6 |
Formula: |
By using formula |
\$| x | = a\$ |
7 |
Hint |
By removing mod we get(+) or (-) |
\$x = a (or) x = - a \$ |
8 |
Step |
Here 'a' is \$5/8\$ |
\$ x + 6 = 5/8 (or) x + 6 = - 5/8 \$ |
9 |
Step |
Adding - 6 on both sides we get |
\$ x + \cancel6 - \cancel6 = 5/8 - 6 (or) x + \cancel6 - \cancel6 = - 5/8 - 6 \$ |
10 |
Step |
After cancellation we get |
\$ x = 5/8 - 6 (or) x = - 5/8 - 6 \$ |
11 |
Hint |
Taking LCM as 8 |
|
12 |
Step |
After simplification |
\$ x = (5 - 48)/8 (or) x = (-5 - 48)/8 \$ |
13 |
Step |
After simplification we get |
\$ x = -43/8 (or) x = - 53/8 \$ |
