Question

Is the equation true, false, or open?
9p + 8 = 10p + 7
A.True; the expressions are the same for all values of the variables. B.False; the expressions are never the same.
C. Open; there is a variable.

Answer 1

9p + 8 = 10p + 7
1 = p
p has a single value
Both sides are the same if p = 1. 17=17
p is a variable, but only has value 1 if equation is satisfied.
