Q. Find the solution of the system of equations.\newline8x5y=148x+y=22 \begin{array}{l} 8 x-5 y=-14 \\ -8 x+y=22 \end{array} \newline(_________,________)
  1. Combine equations: Add the two equations together to eliminate xx.
    (8x5y)+(8x+y)=14+22(8x - 5y) + (-8x + y) = -14 + 22
    Simplify the left side: 8x8x5y+y=0x4y8x - 8x - 5y + y = 0x - 4y
    Simplify the right side: 14+22=8-14 + 22 = 8
    So, 4y=8-4y = 8
  2. Simplify left side: Divide both sides by 4-4 to solve for yy.\newline4y/4=8/4-4y / -4 = 8 / -4\newliney=2y = -2
  3. Simplify right side: Substitute y=2y = -2 into one of the original equations to solve for xx. Let's use the second equation: 8x+y=22-8x + y = 22 Substitute yy: 8x+(2)=22-8x + (-2) = 22 Simplify: 8x2=22-8x - 2 = 22
  4. Divide by 4-4: Add 22 to both sides to isolate the term with xx.8x2+2=22+2-8x - 2 + 2 = 22 + 28x=24-8x = 24
  5. Substitute yy into equation: Divide both sides by 8-8 to solve for xx.8x8=248\frac{-8x}{-8} = \frac{24}{-8}x=3x = -3
