Is p = -1 a solution to the equation 6(p – 4) = -30p?

To know if p = -1 is a possible solution to 6(p – 4) = -30p, plug in -1 for p and see if the equation is true.

6(p – 4) = -30p
6(-1 – 4) = -30(-1)

6(-1 – 4) = -30(-1)
Solve the parentheses.
-1 - 4 = -5

6(-5) = -30(-1)
Multiply.
6 • -5 = -30
-30 • -1 = 30

-30 = 30
This is not true, so p = -1 is NOT a possible solution for the equation 6(p – 4) = -30p.

Hope this helps!

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
