1. Solve by substitution or elimination method:

3x – 2y = 26
-7x + 3y = -49

2. Solve by substitution or elimination method:

4x – 5y = 14
-12x + 15y = -42

3. Solve by substitution or elimination method:

-2x + 6y = 19
10x – 30y = -15


Second part of problems:


1. Plot the graph of the equations 2x - 3y = 5 and 4x - 6y = 21 and interpret the result.
2. Plot the graph of the equations 4x - 6y = 12 and x - 5y = 10 and interpret the result.
3. Plot the graph of the equations 8x - 4y = 12 and -4x + 2y = -6 and interpret the result.

Jenzy, can you solve this: 3x - 5 = x + 3
