If it has one solution, name it.5. 2x – y = 1 6. x = 1 7. 3x + y = –3y = –3 2x + y = 4 3x + y = 3163830469905151755469902840309472698. y = x + 2 9. x + 3y = –3 10. y – x = –1x – y = –2 x – 3y = –3 x + y = 31863188036628626116549852192368036611. x – y = 3 12. x + 2y = 4 13. y = 2x + 3x – 2y = 3 y = -12 x + 2 3y = 6x – 6186318556632877479100268521923555663 ................
