3x 5=5x 2 - Microsoft Windows Vista Home Premium with Service Pack 1: Windows

5x (-3x) = 2x -3x - -3x = 0
The equation then becomes 2x=10 2x/2 = x and 10/2 =5
then x=5. does it work 5x5=10+3*5 YES

For 3x(7x+6x)=0, x=0
For 3x(7x+6x)=1, x=1/39
For 3x(7x+6x)=2, x=2/39
For 3x(7x+6x)=3, x=3/39 or 1/13
For 3x(7x+6x)=4, x=4/39
And so on...

5x -2(x-2) = 6 -2(-3x-3)
5x -2x +4 = 6 +6x +6 (use the distributive property)
3x + 4 = 6x + 12 (collect terms)
4 = 3x + 12 (subtract 3x from both sides to get all x on one side)
-8 = 3x (subtract 12 from both sides to get only x on one side)
-8/3 = x (divide both sides by 3 to get x by itself)

Check
5(-8/3) -2((-8/3)-2) = 6 - 2(-3(-8/3)-3)
-40/3 -2(-8/3-6/3) = 6 - 2(8-3)
-40/3 -2(-14/3) = 6 -2(5)
-40/3 + 28/3 = 6 - 10
-12/3 = -4 (yes)

(2x - 3y)(3x + 2y) = 2x*3x + 2x*2y - 3y*3x - 3y*2y
= 6x^2 + 4xy - 9xy - 6y^2
= 6x^2 - 5xy - 6y^2 You multiply each element in the first set of brackets by each element in the second set of brackets and then consolidate like terms and arrange them in sequence of powers, first x and then y. So:
2x by 3x = 6x squared
2x by 2y = 4xy
-3y by 3x = -9xy
-3y by 2y = 6y squared

6x squared -5xy + 6y squared

I THINK YOU WANT TO KNOW THE VALUE OF X
X+4+2/3 = 6
(3X +12+2)/3 = 6
3X+14 = 3*6
3X + 14 =18
3X = 18 - 14
3X = 4
X = 4/3
X = 1.333 this is answer

Do you mean "graph y=3x+x^2-3" or "solve 3x+x^2=3"?

To graph y=3x+x^-3 press Y=.

Type 3 ALPHA X + ALPHA X ^ 2 - 3 ENTER

Press GRAPH to see the graph.

[3(x-5)-4(-3x+2)]-[4(6-x)]
[(3x-15)-(12x+8)]-(24-4x)
(-9x-23)-(24-4x)
-13x-(-1)
this is 9th grade stuff.

I am not quite sure what you are asking...

(1) if asking for graphing y= -2/3x+2, then press [diamond] [F1: Y=] type in .2/3x +2, see graph by [diamond][graph]

(2) if asking for graphing y= -2/3x+a, where a=3x, then first archive a=3x in Home screen by [home], type 3x [sto] a, then go back to y= menu, and type -2/3x+a in Y1

(3) if asking for graphing an equation that is dependent on 2 variables at the same time, use x-y-z axis (aka, change mode to graphing 3-D by [mode]graph [5:3D]) then enter desired equation in y= menu using Z function in terms of x and y aka z(x,y)= ...)

Just plug in one side of the equation and find the answer. Then plug in the other side and compare answers.

B. 2((2-Y)/3)-Y=3
2(2-Y)-Y=9
4-2Y-Y=9
-3Y=9-4
-3Y=5
-Y=5/3
Y=-1.67

A. 3X+(-1.67)=2
3X-1.67=2
3X=2+1.67
3X=3.67
X=3.67/3
X=1.22
