system of linear equations

Determine whether ordered pair is a solution of the system of linear equations:

x + y = 8

3x + 2y = 21

(2, 4) b. (5, 3)

Solve system of linear equations by graphing:

x + y = 4

x – y = 2

Solve system of linear equations by the substitution method:

y = 3x + 1

4y – 8x = 12
