You can start off by distributing the x-variables and using the LCM of 5 and 12
5 = 5x1
12= 2x2x3
LCM: 1x2x2x3x5= 60
We could also determine the LCM of 13 and 7 (y-variables), since they are both prime numbers.
13x7= 91
The LCM is 91.

13x7= 91
The LCM is 91.
The first equation can be multiplied by –12 and the second equation by 5 to eliminate x.
