Answer 3

thought that was done =)

Answer 4

there is still the other part of it and 1 more question

Answer 5

hmm not sure what's expected

the equation is true for x = -1/2 :)

Answer 6

and then the next part says "This means that the equation is true for (all one or no) number(s).

Answer 7

ohhh all, one, and no

well, the equation is ONLY TRUE if x = -1/2
if x = 3, no dice
if x = 5, no dice
if x = -9, no dice

so, the equation is only true for x = -1/2 ONLY
so, is true for one number/value only

Answer 8

see it?
notice, let's say, we use hmmm 7
\(4x-5(2x+1)=6x+1\qquad {\color{brown}{ x=-\frac{1}{2} }}
\\ \quad \\
4\cdot -\frac{1}{2}-10\cdot -\frac{1}{2}-5=6\cdot -\frac{1}{2}+1
\\ \quad \\
-2+5-5=-3+1\implies -2=-2\qquad \checkmark
\\ \quad \\ \quad \\

4x-5(2x+1)=6x+1\qquad {\color{brown}{ x=7 }}
\\ \quad \\
4\cdot 7-10\cdot 7+5=6\cdot 7+1
\\ \quad \\
28-75=43\implies -47\ne 43\)

notice, is true, or the equation actually EQUATES, only if x = -1/2

Answer 9

so it is one?
