Charlie used these steps to solve the equation 6x+5=1+2(3x+2)6x+5=1+23x+2. Which choice describes the meaning of his result, 5

zaharov [31]

We have that
[6x+5]=1+2*(3x+2)
[6x+5]=1+2*3x+2 --------> is not correct ------->1+ 2*(3x+2)=1+2*3x+2*2

then
[6x+5]=1+6x+4---------------> [6x+5]=[6x+5]

this equation is an identity, all real numbers are solutions.
