solve for x:6+9x+(-2)=7x+(-2)(x+-4)?

Question

Need help so that I can help my daughter out...once again. I really appreciate the help!

I truly am not trying to deceive any one, but can understand how you would think otherwise...any way I appreciate the help, but really need to know how to work the problem. Thank you!

Answer 1

6 + 9x -2 = 7x - 2x +8
4 + 9x = 5x + 8
4x = 4
x = 1

Answer 2

X=5

6+9x+(-2)=7x+(-2)(x+-4)
-12+9x=7x+-2x+8
-12+9x=5x+8
4x=20
x=5

Answer 3

solve for x
6+9x+(-2)=7x+(-2)(x+4) equation
6+(-2)+9x=7x+(-2x)+(-8) distribute -2
4+9x=5x-8 combine like terms
4x=-12 subtract 5x and 4 on both sides
x= -3 divide by 4 both sides

substitute -3 to all x
6+9(-3)+(-2)=7(-3)+(-2)(-3+4)
6+(-27)+(-2)=(-21)+(-2)(1)
-23=-23

so im right!!!

Answer 4

First you need to combine like terms. That means to combine all the variables and "naked" numbers. So you minus 7x from the 9x and get 2x, you do that so you get one of the variables to the left side of the equals sign.Then you need to get the other variable to the left side of the equals sign so you have to minus the x from bothe sides so you end up with 6+x=(-2)(-4) then you need to get the naked number to the oppisite side of the equals sign so you minus six from negative two and end up with four so now you have x=4(-4) so then you times four and negative four and end up with x= -16 i'm pretty sure this is right sorry if it's wrong

Answer 5

6+9x-2=7x-2x-+8 (foiled)
9x+4= 5x+8 (solved each part first)
4x+4= 8 (subtracted 5x from 9x)
4x=4 (subtracted 4 from 8)
x= 1 (divide each member by 4)

Answer 6

6 + 9x - 2 = 7x - 2x + 8 which equals to 4 = -4x + 8 which equals to -4 = -4x and the answer is x=1.

if you can't answer that, wait till she goes into calculus, dang I hate that math!

Answer 7

nice try to decieve us ..
anyway , x = 1
