Answer:
1.Examples. 10x - 3y = 5 and -2x - 4y = 7 are linear equations in two variables. ... The point x = 8 and y = 3 is also a solution of the equation 2x - 3y = 7 since 2(8) - 3(3) = 16 - 9 = 7. The point x = 4 and y = 6 is not a solution of the equation 2x - 3y = 7 because 2(4) - 3(6) = 8 - 18 = -10, and -10 6= 7.

3.A linear system of two equations with two variables is any system that can be written in the form. ... A solution to a system of equations is a value of x and a value of y that, when substituted into the equations, satisfies both equations at the same time.
4.The number r is called the constant of the equation ax + by = r. Examples. 10x - 3y = 5 and -2x - 4y = 7 are linear equations in two variables. ... The point x = 8 and y = 3 is also a solution of the equation 2x - 3y = 7 since 2(8) - 3(3) = 16 - 9 = 7.
