Q. Solve the system of equations.\newline11x+4y=467x4y=10x=y= \begin{array}{l} 11 x+4 y=-46 \\ 7 x-4 y=10 \\ x=\square \\ y=\square \end{array}
  1. Identify variable to eliminate: Identify the variable to eliminate. In this case, we can eliminate 'yy' as the coefficients are the same in magnitude but opposite in sign.
  2. Identify operation to eliminate variable: Identify the operation to eliminate the variable. Here, we add the equations as the coefficients of 'yy' are opposite.
  3. Add equations to eliminate variable: Add the equations to eliminate yy. (11x+4y)+(7x4y)=46+10(11x + 4y) + (7x - 4y) = -46 + 1011x+4y+7x4y=3611x + 4y + 7x - 4y = -3618x=3618x = -36
  4. Solve for x: Solve for 'x'. Dividing both sides of the equation by 1818 gives us x=3618x = -\frac{36}{18}.\newlinex=2x = -2
  5. Substitute xx into equation to solve for yy: Substitute x=2x = -2 into one of the original equations to solve for 'yy'. Let's use the first equation: 11x+4y=4611x + 4y = -46.
    11(2)+4y=4611(-2) + 4y = -46
    22+4y=46-22 + 4y = -46
  6. Solve for y: Solve for yy. Add 2222 to both sides of the equation to isolate the term with yy.\newline4y=46+224y = -46 + 22\newline4y=244y = -24\newlineDivide both sides by 44 to find yy.\newliney=24/4y = -24 / 4\newliney=6y = -6
  7. Write the solution as a coordinate pair: Write the solution as a coordinate pair.\newlineThe solution is (2,6)(-2, -6).
