Lesson Steps

Step Type Explanation Answer

1

Problem

Solve the equation
\$| -x | = -4/6 \$

2

Formula:

By using formula

\$| x |\$ = a

3

Hint

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

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

4

Step

Here 'a' is \$-4/6\$

\$ -x = -4/6 (or) -x = -(-4/6)\$

5

Step

After multiplication we get

\$ -x= - 4/6 (or) -x = 4/6 \$

6

Step

Multiplying "-" on both sides we get

\$-(-x) = -(-4/6) (or) -(-x) = - 4/6\$

7

Step

After multiplication we get

\$ x = \cancel4^2/\cancel6^3(or) x = - \cancel4^2/\cancel6^3 \$

8

Step

After cancellation we get

\$ x = 2/3(or) x = -2/3 \$

9

Answer

D
