Of equal importance is quit watching that cute little girl to your left
in front of you, and listen to your big-mouth-teacher:cool:

Never quit looking at the cute girl on your left. She might bring a whole lot of fun into your life.

On the other hand, your big-mouthed teacher might also bring a whole lot of fun into your life if you learn what he's teaching. Because maths can be fun. And even if you don't find it so, learning the lessons might get you the sort of exam results that get you a good job and a good income, and the cute girls often come with that too.

see I was thinking this too, yet was not sure how to write it.

Yet if i did it this way it confused me too as i would have gone and got

-36x-24=10

?

The question says: their sum is decreased by 6. It does not say that their sum is multiplied by 6. I am surprised that you took those brackets for multiplication. They were just to explain you that their sum had to be reduced by 6.

Oh how I wish it was the cute person I was watching that was what was my issue! For me besides this question and all my others it's just I have too many formulas I get confused. Even when I take tests I get the answers but confuse the signs.

I just am a learner that needs to be told a formula, have a chance to do the formula, and then have someone watch me and see what I am doing wrong. Otherwise the 30 mins of lecture just is not retained. Thank goodness for this website as I have no one else that understands math around me.

I took it as multiplication because I was reading it as the distributive property.

"(x + 4+5x)-6" doesn't have multiplication. You treated it as -6(x + 4 + 5x), which is different.
