Im trying to solve the equation 5x=10-3x


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

3x(7x+6x)


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...

2x^5+4x^4-3x^2+7,7x^4-3x^3+x^2-9


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 - 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

2x2-3x+5=0 solving the quadratic equation


Here you are :
2X2-3x+5=0 => 4-3x+5=0; (2X2=4) => -3x+9=0; (4+5=9) => 9 = 3x; (-3x moved to the right-hand side and it became 3x) => 9/3=x; (3 moved to the right hand side, so it becomes 1/3, i.e 1/3X9= 9/3) i.e. x=9/3 => x=3
Hence x equals to 3.

You can add or remove the explanation/description, I simply add them to make you understand.
If you need help, let me know.

Good luck.

Thanks for using FixYa.

X+4+2/3=6


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
