Q. Solve the system of equations.\newline6y+11x=364y+7x=24x=y= \begin{array}{l} -6 y+11 x=-36 \\ -4 y+7 x=-24 \\ x=\square \\ y=\square \end{array}
  1. Write Equations: Write down the system of equations.\newlineWe have the following system of equations:\newline6y+11x=36-6y + 11x = -36\newline4y+7x=24-4y + 7x = -24\newlineWe need to find the values of xx and yy that satisfy both equations.
  2. Solve for x: Solve one of the equations for one variable.\newlineLet's solve the second equation for x:\newline4y+7x=24-4y + 7x = -24\newline7x=4y247x = 4y - 24\newlinex=4y247x = \frac{4y - 24}{7}\newlineNow we have xx expressed in terms of yy.
  3. Substitute xx: Substitute the expression for xx into the first equation.\newlineSubstitute x=4y247x = \frac{4y - 24}{7} into the first equation:\newline-6y + 11\left(\frac{4y - 24}{7}\right) = -36\(\newlineNow we need to solve for \$y\).
  4. Eliminate Fraction: Multiply both sides of the equation by \(7\) to eliminate the fraction.\(\newline\)\(7(-6y) + 11(4y - 24) = -36 \times 7\)\(\newline\)\(-42y + 44y - 264 = -252\)\(\newline\)Now we combine like terms.
  5. Combine Terms: Combine like terms and solve for \(y\). \(\newline\)\[2y - 264 = -252\]\(\newline\)\[2y = -252 + 264\]\(\newline\)\[2y = 12\]\(\newline\)\[y = \frac{12}{2}\]\(\newline\)\[y = 6\]\(\newline\)We have found the value of \(y\).
  6. Find \(y\): Substitute the value of \(y\) back into the expression for \(x\).
    \(x = \frac{4y - 24}{7}\)
    \(x = \frac{4(6) - 24}{7}\)
    \(x = \frac{24 - 24}{7}\)
    \(x = \frac{0}{7}\)
    \(x = 0\)
    We have found the value of \(x\).
