Question

Which values of P and Q result in an equation with exactly one solution?
Qx+12=13x+P

a. Q=12 and P=-12
b. Q=-13 and P=13
c. Q=12 and P=12
d. Q=-13 and P=-13

Answer 1

Another question for my impossible math question file.

All of the given pairs of values result in an equation with exactly one solution, as will any pair such that Q≠13 and P≠12.

For Q=13 and P≠12, there is no solution.
For Q=13 and P=12, there will be an infinite number of solutions.

Answer 2

Its all of the answers in that question
