1 |
Problem |
Calculate the equation |
|
2 |
Formula: |
By using formula |
\$| x | = | x |\$ |
3 |
Hint |
By removing mod we get(+) or (-) |
\$x=x (or) x=-x \$ |
4 |
Step |
By simplifying we get |
\$ 10x + 11 = -7x (or) 10x + 11 = -(-7x) = 7x \$ |
5 |
Step |
Move 'x' variable terms right hand side and constant terms left hand side |
\$ 10x + 7x = -11 (or) 10x - 7x = -11 \$ |
6 |
Step |
After simplification we get |
\$ 17x = - 11 (or) 3x = -11 \$ |
7 |
Step |
Dividing on both sides by '17' and '3' |
\$ \cancel17/\cancel17x = -11/17 (or) \cancel(3)/\cancel(3)x = -11/3 \$ |
8 |
Step |
After cancellation we get |
\$ x = -11/17 (or) x = -11/3 \$ |
