I'm stuck on how to use the elimination by addition method to slove for this system.
5x - y = 6
10x - 2y = 12 This question is from textbook Elementary and Intermediate Algebra

Solve by elimination:
1) 5x - y = 6 Multiply this equation -2
2) 10x - 2y = 12
1a) -10x + 2y = -12 Now add this to equation 2)
2) 10x - 2y = 12 The result!
0 = 0
The two equations represent the same line so there are an inifinite number of solutions.
