Answer: X=2.7

Step-by-step explanation:

25*2-8x=12x-4

50-8x = 12x-4

subtract 50 from both sides

-8x = 12x-54

subtract 12x from both sides

-20x= -54

divide both sides by -20

X=2.7

Answer:x=2/5

Step-by-step explanation:

25x2-8x=12x-4

25x2-8x-12x+4=0

25x2-20x+4=0

25x2-10x-10x+4=0

5x(5x-2)-2(5x-2)=0

(5x-2)(5x-2)=0

5x-2=0 and 5x-2=/

5x=2 and 5x=2

X=2/5
