Answer:
Let the number be x
so, x/4 = x-3
x = 4(x-3)
x= 4x-12
x-4x = -12
-3x = -12
x= 12/3
x = 4

Answer:X=4
Step-by-step explanation:
Congruent triangles method
AB/DB=BC/EC
10-x+x/10-x=3+2/3
10/10-x=5/3
30=50-5x
30-50=-5x
-20=-5x
X=4
3(x^2 -x) -x
6x^2 -3x-x
6x^2 - 4x
we can simplify it more by take 2x as comman factor
so , 2x ( 3x -2 )
