Question

why should the equations (x-1)(x+3)=17+x and (x+3)(x-1)=17+x)
have the same solution set?

HELP PLEASE

Answer 1

Answer:

Both of them are simultaneous equation..

Answer 2

Step-by-step explanation:

Because the commmutative property of multiplication says that (x) (y) = (y) (x)

so here (x-1) (x+3) and (x+3) (x-1) are the same thing i.e they both are equal.

Hence they have the same solution set
