Solve: 5.6 = 3.1 – 12.5|1 – 0.8x|

5.6 = 3.1 – 12.5|1 – 0.8x|
2.5 = –12.5|1 – 0.8x|
–0.2 = |1 – 0.8x|
Finish the steps shown to find the possible value(s) for x that make the statement true.

x = –1 or x = 1.5
x = 1 or x = –1.5
x = 0

Answer:

There are no solutions.

Explanation:

Questions:

  • Solve: 5.6= 3.1 – 12.5|1 – 0.8x|

To find:

  • The value of x.

Solutions:

  • 5.6= 3.1 – 12.5|1 – 0.8x|

First, do switch sides.


\Longrightarrow:\sf=5.6

Multiply by 10 from both sides.


\Longrightarrow: \sf3.1*10-12.5

Solve.

31-125|1-0.8x|=56

Subtract by 31 from both sides.


\Longrightarrow: \sf1-0.8x\right

Solve.


\Longrightarrow: \sf-125\left

Divide by -125 from both sides.

Solve.


\Longrightarrow: \sf{(-125\left|1-0.8x\right|)/(-125)=(25)/(-125)=\boxed{\sf{No\ solutions.}}}

  • Therefore, the correct answer is "D. There are no solutions."

I hope this helps, let me know if you have any questions.
