Question

Is 8 a solution of x < -1 or x > 7?

Answer 1

plug 8 in for x into each

Answer 2

so 8x<-1 or8>7?

Answer 3

"8 is a solution" means "8 is x"
So you where you see an x, you put the eight there instead and see if it works out
8< -1 means eight is less than -1.....is eight less than -1? No, its more
So 8 is not a solution for this one
8>7 means eight is more than seven....it is
So 8 is a solution for x, but only in x>7

Answer 4

8 is a solution of x>7
