What is common solution of both 2x+y=53x+2y=8 |
|
Answer» X=2 y=1 \xa0Given equations are2x+y-5=03x+2y-8=0\xa0By cross multiplication rule,{tex}\\displaystyle\\frac{x}{-8+10}=\\frac{y}{-15+16}=\\frac{1}{4-3}{/tex}{tex}\\displaystyle\\implies\\frac{x}{2}=\\frac{y}{1}=\\frac{1}{1}{/tex}{tex}\\implies\\;x=2\\;\\text{and}\\;y=1{/tex}{tex}\\therefore\\textbf{The solution is x=2 and y=1 }{/tex}\xa0\xa0 |
