x = 8; y = -6

Step-by-step explanation:

We have a system of equations.

First, let's multiply both sides of each equation by the LCM of both denominators of that equation to eliminate all denominators.

First equation:

The equation above is the simplified first equation.

Second equation:

The equation above is the simplified second equation.

The simplified system of equations is:

The x term of both equations is 6x. If we multiply both sides of the second equation by -1 to get a first term of -6x, then when it is added to 6x, the x terms are eliminated.

Now we rewrite the first simplified equation as it is. Below it, we write the second equation multiplied by -1 on both sides. Then we add the equations.

Add the equations to get:

Now we substitute -6 for y in the first simplified equation and solve for x.

Solution: x = 8; y = -6

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
