Explanation

Answer

Problem

Solve the equation
\$ | -x | = -76 \$

Formula:

By using formula

\$| x | \$= a

Hint

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

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

Step

Here 'a' is -76

\$ -x = -76 (or) -x = -(-76)\$

Step

After multiplication we get

\$ -x= - 76 (or) -x = 76 \$

Step

Multiplying "-" on both sides we get

\$-(-x) = -(-76) (or) -(-x) = - 76\$

Step

After multiplication we get

\$ x= 76 (or) x = - 76 \$
