Andre tried to solve the equation 1/4(x+12)=2 what was his mistake?
GarryVolchara [31]

Step-by-step explanation:

1. 1/4(x + 12)=2 - first isolate X'

         - 12 -12

2. 1/4(x) = -10  - 1/4  since its a fraction, you'll have to subtract not divide

-1/4    - 1/4

3. x = -10.25

Andre did the first step correctly, but on the second step he just divided 1.4 by -10, instead of subtract 1/4 from both sides.

(2x/3)-(5x/9)-(x/6)-(5x/12)=13/2 this equation is equivalent to:
agasfer [191]

Answer:

-17x=234

Step-by-step explanation:

Given that:

\dfrac{2x}{3}-\dfrac{5x}{9}-\dfrac{x}{6}-\dfrac{5x}{12}=\dfrac{13}{2}

\dfrac{72x-60x -18x-45x }{108} = \dfrac{13}{2}

\dfrac{-51x }{108} = \dfrac{13}{2}

-102x =    1404

-\dfrac{102x}{6} = \dfrac{1404}{6}

-17x = 234
