Question

i have this question that i dont get plz help-2|2.2x-3.3|=-6.6

Answer 1

Step-by-step explanation:

Absolute value of a number gives the positive quantity of the number.

For instance,

$|3|=3, |-3|=3$

From this example, therefore we know that

$\text{If }|x|=a,\text{ then }x=a\text{ or } -a.$

--------------------------------------------

In this question,

$-2|2.2x-3.3|=-6.6$

$|2.2x-3.3|=3.3$

$2.2x-3.3=3.3\text{ or } -3.3$

$2.2x=3.3+3.3 \text{ or }-3.3+3.3$

$2.2x=6.6\text{ or } 0$

$x=3\text{ or } 0$

Answer 2

Answer:

X = 3

Step-by-step explanation:

2(2.2x - 3.3) = 6.6

4.4x - 6.6 = 6.6

4.4x = 6.6 + 6.6

4.4x = 13.2

4.4x = 13.2

4.4 4.4

X = 3
