Question

Solve the equation. |k + 6| = 3

Question 7 options:

{–3, 9}


{–3, 3}


{–9, –3}


{all real numbers greater than or equal to –9 and less than or equal to –3}

Answer 1

Explanation:

k= {-3,-9}

Because || always gets positive numbers.

For example |-5|=5, and |5|=5.

so |-9+6|=|-3| which is |-3|=3

and |-3+6|=|3| which is equal to 3.

Answer 2

c) k = {-9,-3}

Explanation:

Given equation,

→ |k + 6| = 3

Now the value of k will be,

→ |k + 6| = 3

→ k + 6 = 3 || → -(k + 6) = 3

→ k = 3 - 6 || → -k = 3 + 6

→ [ k = -3 ] || → [ k = -9 ]

Hence, value of k is -3 & -9.
