Question

x:4+x=3.75

Answer 1

x : 4 + x = 3,75

x : ( 4-1 ) = 3,75

x : 3 = 3,75

x = 3,75 x 3

x= 11,25

Answer 2

X x1/4 + X = 3,75 

X x ( 1 + 1/4 ) = 3,75

X x 1/1/4 = 3,75

X x 1,25 = 3,75

X           = 3,75 : 1,25

X           =3

Answer 3

x : 4 + x = 3,75

x : ( 4-1 ) = 3,75

x : 3 = 3,75

x = 3,75 x 3

x= 11,25
