If the equation ar+b=cr + d has no solution, like in the example below, what must be true about a b c and d?

Answer:

See below.

Step-by-step explanation:

For an equation like [tex]\displaystyle \large{ar+b=cr+d}[/tex] to have no solution, the equation has to be false.

To make an equation false, we let a = c. That’d make a and c have same value, when we transport cr to subtract ar, we’ll get 0.

So if a = c, the equation is [tex]\displaystyle \large{b=d}[/tex] now that we have b = d. The equation has to be false to have no solutions, hence b and d must not equal to one another.

Summary

  • When a = c, the new equation is b = d as ar and cr having same value, when subtracted, the remain is 0+b=d.
  • b = d means that the value of b and d are equal but that makes the solutions to be infinitely many. Therefore, we cannot let b = d.
  • From second, b ≠ d.
  • a = c but b ≠ d
