Determine whether the system of linear equations has one and only one solution, infinitely many solutions, or no solution. 0.3x − 0.2y = 0.4 −0.2x + 0.5y = 0.1

and

Step-by-step explanation:

We have two linear equations

Using the methond of elimination of variables, we will mutiply the first equation by 0.2 and the second one by 0.3 to have the same value of the varible x.

Then

Adding both equation we will eliminate the varible x

Then the value of y is

Now with the value of y we can find x, using the value of y in the first equation we have:

where are the options?
