well, is it true for all values of x? How about x=0?
2 = 11
Nope.
So, try to find a value for x which makes it true, or show that there is none at all.
5x+2=6x+11
a. Open; there is a variable
b. True; the expressions are the same for all values of the variables
c. False; the expressions are never the same
2 = 11
Nope.
So, try to find a value for x which makes it true, or show that there is none at all.
5x=6x+9 then subtract 6x to get -1x=9. divide by 1 to get x=-9. this make the equation true. Therefore it is open.
