If -6(2x+1)=-4+10, then x= my ass

[mendacity13]

Got my car fixed and my school books today. Also a $58.00 speeding ticket. Hooray!

And anybody who understands these:

5x - {2x=4 (x-3)} (simplify... and what's the difference between { and (?)
If -6(2x 1)= -4x 10, then x = ?
|-26 10| (this one says evaluate... what do the | mean?)
2x-6<-9 7x (solve for x

{ (?)}

I believe you would solve the problem in { } before ( )
so first {} then () to receive the total number so in the first one I think the 2nd one x=0

(3x-5)(2x7)Simplify answer is 14x(3x-5)

Thank you, whoever you are!

5x - {2x=4 (x-3)} (simplify... and what's the difference between { and (?)

that's weird. In all my math, I've never seen an equation like that. I imagine you just eval 5x - {2x=4x-12}, the distribute the - sign to the {} so that it's 5x-2x=12-4x, then 3x=12-4x, then 7x=12, x = 12/7, that's my guess.

If -6(2x 1)= -4x 10, then x = ?

I assume the (2x 1) is 2x to the first power, which is just 2x. This is
-12x = -4x^10 (the ^ is used in ascii to denote powers). You can divide both sides by x to get -12 = -4x^9 (x^10 = x*x*x*x*x*x*x*x*x*x) then divide by -4 on both sides, so 3=x^9, then x=3^(1/9)

|-26 10| (this one says evaluate... what do the | mean?)

the | | signs mean absolute value. Basically if you take the absolute value of a negative number, it makes it positive.

2x-6<-9 7x (solve for x)

the < or > signs work just like an = sign as far as solving an equation, you're just saying that x is less than a certain value for this equation to be valid

are you still alive?
