Solution for 1/4+2/(a+3)=3/8 equation: 


D( a )

a+3 = 0

a+3 = 0

a+3 = 0

a+3 = 0 // - 3

a = -3

a in (-oo:-3) U (-3:+oo)

2/(a+3)+1/4 = 3/8 // - 3/8

2/(a+3)+1/4-(3/8) = 0

2/(a+3)+1/4-3/8 = 0

(2*4*8)/(4*8*(a+3))+(1*8*(a+3))/(4*8*(a+3))+(-3*4*(a+3))/(4*8*(a+3)) = 0

1*8*(a+3)-3*4*(a+3)+2*4*8 = 0

8*a-12*a-36+88 = 0

52-4*a = 0

(52-4*a)/(4*8*(a+3)) = 0

(52-4*a)/(4*8*(a+3)) = 0 // * 4*8*(a+3)

52-4*a = 0

52-4*a = 0 // - 52

-4*a = -52 // : -4

a = -52/(-4)

a = 13

a = 13
