4/5w-12=2/3w<br> what is the step by step answer to those equation?
Mariulka [41]
Kulay, there is no such thing as a "step by step answer" here.  You seem to want a "step by step solution."

I must assume that by 4/5 you actually meant (4/5) and that by 2/3 you meant (2/3).  Then your equation becomes:

(4/5)w - 12 = (2/3)w. 

The LCD here is 5*3, or 15, so mult. every term by 15:

12w - 180 = 10w.   
Add 180 to both sides, obtaining 12 w - 180 + 180 = 10w + 180.     

Then 12w = 10w + 180.  Simplifying, 2w = 180.    What is w?

Follow the process of completing the square to solve 2x2 + 8x - 12 = 0.
Rom4ik [11]
Please:  Use "^" to denote exponentiation:  <span>2x^2 + 8x - 12 = 0

Reduce this by div. every term by 2:             </span><span>x^2 + 4x - 6 = 0

Here a=1, b=4 and c = -6.  Square half of b, obtaining (4/2)^2 = 4, and add, and then subtract, this 4 to x^2 + 4x - 6:

</span> x^2 + 4x +4  - 4 - 6 = 0.  Rewrite the square as (x+2)^2, obtaining new equation

(x+2)^2 = 10.  Take the sqrt of both sides:   x+2 = plus or minus sqrt(10).

Finally, solve for x:  x = -2 plus or minus sqrt(10).
