Ok!, try to add +4 to both sides of your inequality, please

anonymous · Answer

$$3a-4\le5          Afteradd +4 \to both side then: devide \to 3 then we have: a \le \frac{ 1 }{ 3 }$$

anonymous · Answer

anonymous · Answer

$$a \le \frac{ 9 }{ 3}$$

michele_laino · Answer

@olivia.smiles  here is the procedure:
$$3a-4+4\le 5+4$$

anonymous · Answer

@Michele_Laino $$3a \le 9$$

michele_laino · Answer

well done!

michele_laino · Answer

now divide by 3, your last inequality, please

anonymous · Answer

a is greater then or equal to 3

michele_laino · Answer

are you sure? I think is:
$$\frac{ 3a }{ 3 }\le \frac{ 9 }{ 3 }$$, then?

solomonzelman · Answer

you put the wrong sign, olivia.smiles, you said that "a" is GREATER than or equal to 3, but it is  LESS than or equal to 3.

michele_laino · Answer

@SolomonZelman  from the text I read a is less or equal, so the sigh is $$\le $$

solomonzelman · Answer

I said that it is less than or equal to. Because Olivia said that it is greater or equal.
