|---|---|---|---|
1 |
Problem |
Calculate the equation |
|
2 |
Step |
Adding - 4 on both sides we get |
\$ 5| x + 7 | + \cancel4 - \cancel4 = 15 - 4 \$ |
3 |
Step |
After cancellation we get |
\$ 5| x + 7 | = 11 \$ |
4 |
Step |
Dividing on both sides by '5' we get |
\$ \cancel5/\cancel5| x + 7 | = 11/5 \$ |
5 |
Step |
After cancellation we get |
\$ | x + 7 | = 11/5 \$ |
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 \$11/5\$ |
\$ x + 7 = 11/5 (or) x + 7 = - 11/5 \$ |
9 |
Step |
Adding '- 7' on both sides we get |
\$ x + \cancel7 - \cancel7 = 11/5 - 7 (or) x + \cancel7 - \cancel7 = - 11/5 - 7 \$ |
10 |
Step |
After cancellation we get |
\$ x = 11/5 - 7 (or) x = - 11/5 - 7 \$ |
11 |
Hint |
Taking LCM as 5 |
|
12 |
Step |
After simplification |
\$ x = (11 - 35)/5 (or) x = (-11 - 35)/5 \$ |
13 |
Step |
After simplification we get |
\$ x = -24/5 (or) x = - 46/5 \$ |
