Which of these strategies would eliminate a variable in the system of equations?
2x-5y=13
-3x+2y=13

Answer:
B
Step-by-step explanation:
2x-5y=13.........(1) × 3
-3x+2y=13.......(2) × 2
6x - 15y = 39
-6x + 4y = 26
Adding
6x - 6x - 15y + 4y = 13 + 13
Answer:
Step-by-step explanation:
2x - 5y = 13
-3x + 2y = 13
multiply the top equation by 3 and the bottom one by 2, then add <==
watch...
2x - 5y = 13.....multiply by 3
-3x + 2y = 13....multiply by 2
-----------------
6x - 15y = 39 (result of multiplying by 3)
-6x + 4y = 26 (result of multiplying by 2)
-----------------add
- 11y = 65.....notice how out x terms were eliminated :)
