Answer

Problem

Solve the equation
\$| -x | = 12/16 \$

Formula:

By using formula

\$| x |\$ = a

Hint

By removing mod we get (+) (or) (-)

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

Step

Here 'a' is \$12/16\$

\$ -x = 12/16 (or) -x = -12/16\$

Step

Multiplying "-" on both sides we get

\$-(-x) = - 12/16 (or) -(-x) = - (-12/16)\$

Step

After multiplication we get

\$ x = - \cancel12^3/\cancel16^4(or) x = \cancel12^3/\cancel16^4 \$

Step

After cancellation we get

\$ x = - 3/4(or) x = 3/4 \$
