Answer:
A solution of a system of equations is a list of numbers x , y , z ,... that make all of the equations true simultaneously. The solution set of a system of equations is the collection of all solutions. Solving the system means finding all solutions with formulas involving some number of parameters.

Answer:
Step-by-step explanation:
In this context "solution" means a point whose x- and y-coordinates satisfy both equations.
If we're given the two linear equations x + y = 3 and 2x - y = 7, we can solve them by addition and subtraction (among other methods):
3x = 3 + 7, or 3x = 10, or x = 10/3.
Substitute this result into x + y = 3 to find the corresponding y value;
10/3 + y = 3, or 10/3 + y = 9/3, or y = 1/3.
Then the "solution" is the point (10/3, 1/3).
