[1] y = -x + 5
3x + 3•(-x +5) = 10
0 = -5 => NO solution
Answer:
The identity property
Step-by-step explanation:
.......
the x and y values makes both equations true
Explanation
a linear system is the set of 2 linear equations.
Step 1
the solution to a linear system is the coordiante where the line intersect, this coordiante satisfies both equations, then
the x and y values makes both equations true
