Q. How many solutions does У=−6x−2У = - 6x - 2 12x+2y=−412x + 2y = -4 have
  1. Combine like terms: Combine like terms in the second equation.\newline12x+2y=−412x + 2y = -4\newline2y=−4−12x2y = -4 - 12x\newliney=−2−6xy = -2 - 6x
  2. Compare equations: Compare the two equations.\newliney=−6x−2y = -6x - 2 and y=−2−6xy = -2 - 6x are the same equation.\newlineSo, they are the same line and have infinite solutions.
