Q. 6x+2y=36x+y=3 \begin{array}{l} 6 x+2 y=3 \\ 6 x+y=3 \end{array} \newlineConsider the given system of equations. How many (x,y) (x, y) solutions does this system have?\newlineChoose 11 answer:\newline(A)No solutions\newline(B) Exactly one solution\newline(C) Infinitely many solutions\newline\newline(D) None of the above
  1. Analyze System of Equations: Analyze the given system of equations.\newlineWe have the system:\newline{6x+2y=36x+y=3 \begin{cases} 6x + 2y = 3 \\ 6x + y = 3 \end{cases} \newlineWe want to determine the number of solutions for this system.
  2. Subtract Equations to Eliminate x: Subtract the second equation from the first equation to eliminate x and solve for y.\newlineSubtracting the second equation from the first, we get:\newline(6x+2y)(6x+y)=33 (6x + 2y) - (6x + y) = 3 - 3 \newline6x+2y6xy=0 6x + 2y - 6x - y = 0 \newline2yy=0 2y - y = 0 \newliney=0 y = 0
  3. Substitute y = 00: Substitute y = 00 into one of the original equations to solve for x.\newlineLet's substitute y = 00 into the second equation:\newline6x+y=3 6x + y = 3 \newline6x+0=3 6x + 0 = 3 \newline6x=3 6x = 3 \newlinex=36 x = \frac{3}{6} \newlinex=12 x = \frac{1}{2}
  4. Check Solution: Check the solution (x = 11/22, y = 00) in both original equations to ensure it satisfies both.\newlineFirst equation check:\newline6x+2y=3 6x + 2y = 3 \newline6(12)+2(0)=3 6(\frac{1}{2}) + 2(0) = 3 \newline3+0=3 3 + 0 = 3 \newline3=3 3 = 3 (True)\newlineSecond equation check:\newline6x+y=3 6x + y = 3 \newline6(12)+0=3 6(\frac{1}{2}) + 0 = 3 \newline3+0=3 3 + 0 = 3 \newline3=3 3 = 3 (True)
