{0,4 x+0,1 y=1 -0,1 x-0,4 y=-1.

Question

{0,4 x+0,1 y=1 -0,1 x-0,4 y=-1.

Answer 1

To solve the system of linear equations:

we can use the method of substitution or elimination. Here, we'll use the elimination method.First, let's multiply the first equation by 10 to eliminate the decimals:

Next, let's multiply the second equation by 10 as well:

Now we have the system:

Next, we'll multiply the second equation by 4 to align the coefficients of

:

Now we have:

Add the two equations together to eliminate

:

This simplifies to:

Solving for

:

Now substitute

back into the first equation:

Solving for

:

So the solution to the system of equations is:

Thus, the solution is \((2, 2)\).
