Q. Solve the system of equations.\newline3y4x=113y5x=61x=y= \begin{array}{l} -3 y-4 x=-11 \\ 3 y-5 x=-61 \\ x=\square \\ y=\square \end{array}
  1. Write Equations: Write down the system of equations.\newlineWe have the following system of equations:\newline3y4x=11-3y - 4x = -11\newline3y5x=613y - 5x = -61\newlineWe need to find the values of xx and yy that satisfy both equations.
  2. Add to Eliminate y: Add the two equations together to eliminate y.\newlineBy adding the two equations, we get:\newline(3y4x)+(3y5x)=11+(61)(-3y - 4x) + (3y - 5x) = -11 + (-61)\newlineThe y terms cancel out, and we are left with:\newline4x5x=1161-4x - 5x = -11 - 61
  3. Combine Terms for x: Combine like terms and solve for x.\newline4x5x=9x-4x - 5x = -9x\newline1161=72-11 - 61 = -72\newlineSo we have:\newline9x=72-9x = -72\newlineNow, divide both sides by 9-9 to solve for x:\newlinex=72/9x = -72 / -9\newlinex=8x = 8
  4. Substitute xx for yy: Substitute the value of xx into one of the original equations to solve for yy. Let's use the first equation: 3y4x=11-3y - 4x = -11 Substitute x=8x = 8: 3y4(8)=11-3y - 4(8) = -11 3y32=11-3y - 32 = -11
  5. Isolate y Term: Add 3232 to both sides to isolate the term with yy. \newline3y32+32=11+32-3y - 32 + 32 = -11 + 32\newline3y=21-3y = 21\newlineNow, divide both sides by 3-3 to solve for yy:\newliney=213y = \frac{21}{-3}\newliney=7y = -7
