Question

What is the solution to –2|2.2x – 3.3| = –6.6? x = –3 x = 3 x = –3 or x = 0 x = 0 or x = 3

Answer 1

Answer:

The correct answer is - x = 0 or x = 3

Explanation:

Given:

–2|2.2x – 3.3| = –6.6?

Find the first solution

For absolute value is positive

 –2[2.2x – 3.3] = –6.6

solving it:

-4.4x + 6.6 = –6.6

- 4.4x = -6.6 - 6.6

-4.4x = 13.2

x= 3

For negative abolute value

 –2[-(2.2x – 3.3)] = –6.6

4.4x - 6.6 = - 6.6

4.4x = 0

x = 0

Thus, the correct answer is - x = 0 or x = 3
