Q. 4(80+n)=(3k)n4(80+n)=(3k)n\newlineIn the given equation, \newlinekk is a constant. For what value of \newlinekk are there no solutions to the equation?
  1. Distribute the 44: First, let's distribute the 44 on the left side of the equation.\newline4(80+n)=4×80+4×n4(80+n) = 4\times80 + 4\times n\newlineThis gives us:\newline320+4n=(3k)n320 + 4n = (3k)n
  2. Compare coefficients of nn: Now, we want to find the value of kk for which there are no solutions to the equation. This would occur if the equation is inconsistent, meaning that the variable terms cancel each other out and we are left with a false statement.\newlineLet's compare the coefficients of nn on both sides of the equation.\newlineOn the left side, the coefficient of nn is 44.\newlineOn the right side, the coefficient of nn is 3k3k.\newlineFor the equation to have no solution, these coefficients must be equal, and the constant terms must not be equal.\newlineSo we set 44 equal to 3k3k:\newline4=3k4 = 3k
  3. Solve for k: Now, we solve for kk by dividing both sides of the equation by 33.k=43k = \frac{4}{3}
  4. Check constant terms: However, we must check if the constant terms are equal or not. If they are equal, then the equation would have infinitely many solutions instead of no solution.\newlineThe constant term on the left side is 320320, and since there is no constant term on the right side (it is multiplied by nn), they are not equal.\newlineTherefore, the value of k=43k = \frac{4}{3} does not make the equation have no solution. Instead, it makes the coefficients of nn equal on both sides.
  5. Find value of kk for no solution: To have no solution, the coefficients of nn must be equal, and the constant terms must be different. Since the constant terms are already different (320320 vs 00), we need to find a value of kk that does not make the coefficients of nn equal.\newlineHowever, for any value of kk other than 43\frac{4}{3}, the coefficients of nn will not be equal, and the equation will have a solution.\newlineTherefore, there is no value of kk that will make the equation have no solution, as long as kk is not equal to 43\frac{4}{3}.
