<h2>Answer:</h2>
Option: D is the correct answer.
D. There are no solutions.
<h2>Step-by-step explanation:</h2>Since, in the given steps for solving the given linear expression the last step or expression that is obtained is given by:
Now as we know that the modulus of any number can't be negative.
But in the given expression we have that the modulus of a expression is negative (i.e. -0.2)
Hence, such a system has no solution.
Hence, option: D is correct.

Step-by-step explanation:
Similar triangles are triangles which have the same shape but not the same size. This means their angle measures are equal but their side lengths are not instead they are proportional. To solve, we will set up a proportion and solve.
A proportion is two equal ratios set equal to each other. We form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). Out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:
.
To solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
