Answer

Problem

Solve the equation
\$ | x | = -7/14 \$

Formula:

By using formula

\$| x | = a \$

Hint

By removing mod we get + (or) -

\$x = a (or) x = - a\$

Step

Here 'a' is \$-7/14\$

\$ x = 7/14 (or) x = -(-7/14)\$

Step

After simplification we get

\$ x = - \cancel7^1/\cancel14^2 (or) x = \cancel7^1/\cancel14^2 \$

Step

After cancellation we get

\$ x = - 1/2 (or) x = 1/2 \$
