Q. 3x+4(2y)=5x 3 x+4(2-y)=5 x \newline2y=6x 2-y=6 x \newlineConsider the given system of equations. If (x,y) (x, y) is the solution to the system, then what is the value of xy \frac{x}{y} ?
  1. Solve for y: Solve the first equation for y.\newlineWe have the equation 3x+4(2y)=5x3x + 4(2 - y) = 5x.\newlineFirst, distribute the 44 into the parentheses: 3x+84y=5x3x + 8 - 4y = 5x.\newlineNow, isolate the yy term by moving the other terms to the other side: 4y=5x3x8-4y = 5x - 3x - 8.\newlineSimplify the right side: 4y=2x8-4y = 2x - 8.\newlineDivide both sides by 4-4 to solve for yy: y=(2x8)/4y = (2x - 8) / -4.\newlineSimplify the right side: y=0.5x+2y = -0.5x + 2.
  2. Substitute yy into the second equation: Substitute the expression for yy into the second equation.\newlineWe have the second equation 2y=6x2 - y = 6x.\newlineSubstitute yy with the expression found in Step 11: 2(0.5x+2)=6x2 - (-0.5x + 2) = 6x.\newlineSimplify the equation: 2+0.5x2=6x2 + 0.5x - 2 = 6x.\newlineThe 22's on the left side cancel out, leaving us with: 0.5x=6x0.5x = 6x.
  3. Solve for x: Solve for x.\newlineWe have the equation 0.5x=6x0.5x = 6x.\newlineSubtract 0.5x0.5x from both sides to get all xx terms on one side: 0.5x0.5x=6x0.5x0.5x - 0.5x = 6x - 0.5x.\newlineThis simplifies to 0=5.5x0 = 5.5x.\newlineDivide both sides by 5.55.5 to solve for xx: 0/5.5=x0 / 5.5 = x.\newlineThis gives us x=0x = 0.
  4. Substitute xx into the expression for yy: Substitute x=0x = 0 into the expression for yy. We have y=0.5x+2y = -0.5x + 2. \newlineSubstitute xx with 00: y=0.5(0)+2y = -0.5(0) + 2. \newlineSimplify the equation: y=0+2y = 0 + 2. \newlineThis gives us y=2y = 2.
  5. Calculate xy\frac{x}{y}: Calculate the value of xy\frac{x}{y}. \newlineWe have x=0x = 0 and y=2y = 2. \newlineSubstitute these values into the expression: xy=02\frac{x}{y} = \frac{0}{2}. \newlineSimplify the expression: xy=0\frac{x}{y} = 0.
