Q. Find the solution of the system of equations.\newline6x+4y=466x+6y=42 \begin{array}{l} 6 x+4 y=-46 \\ 6 x+6 y=-42 \end{array} \newline(_________,________)
  1. Eliminate x: Subtract the second equation from the first to eliminate x.\newline(6x+4y)(6x+6y)=46(42)(6x + 4y) - (6x + 6y) = -46 - (-42)
  2. Simplify subtraction: Simplify the subtraction. 6x6x+4y6y=46+426x - 6x + 4y - 6y = -46 + 42
  3. Combine like terms: Combine like terms.\newline0x2y=40x - 2y = -4
  4. Solve for y: Solve for y.\newline2y=4-2y = -4\newliney=42y = \frac{-4}{-2}\newliney=2y = 2
  5. Substitute for yy: Substitute y=2y = 2 into one of the original equations to solve for xx.6x+4(2)=466x + 4(2) = -46
  6. Multiply and simplify: Multiply 44 by 22. \newline6x+8=466x + 8 = -46
  7. Subtract from both sides: Subtract 88 from both sides.\newline6x=4686x = -46 - 8
  8. Combine numbers: Combine the numbers on the right. 6x=546x = -54
  9. Divide to solve for x: Divide both sides by 66 to solve for xx.\newlinex=54/6x = -54 / 6\newlinex=9x = -9
