Explanation:
A system of equations is a set of equations with the same unknowns. A
Linear equation system is a system of equations in which each equation is linear. A solution of a system is a mapping of values for unknowns that makes
true each of the equations. Solving a system means finding all the solutions in the system.
Here's an example of a system of linear equations with two unknowns:
Equation 1
Equation 2 b
2x and 5
x 4 and 7
We can check that x 3 and y 1 is a solution of this system.
Equation 1 Equation 2
