Answer:
<h2> (-1,1)</h2>
Step-by-step explanation:
Given system is

If we graph, the solution would be the interception point between these two lines, because each linear equation represents a line. The lines are attached.
In the graph, you can observe that the solution is the point (-1,1), that is x = -1 and y = 1.
Now, if we want to solve this system by another method, we can just sum both equations and solve for <em>x</em>


Then, we replace this value in one equation to find the other value

Therefore, the solution is (-1,1)
The highlighted part of the triangle is an angle. It is on the inside of the triangle and formed by two sides coming together.
