X=7

30 =25+ 1/5 of 25
4x-4 =20+1/5 of 20 (=24)
4x-4=24
4x=28
X=7
24/20= 1.2

Answer:


\boxed{\boxed{\bf x = 7}}

Explanation:


\sf \cfrac{4x - 4}{20} = \cfrac{30}{25}


\sf 4x - 4 = \cfrac{(20)(30)}{25}


\sf 4x - 4 = \cfrac{600}{25}


\sf 4x - 4 = 24


\sf 4x = 24 + 4


\sf \cfrac{4x}{4} = \cfrac{28}{4}


\sf x = 7
