Why bvp4c not works?

I have an error in using bvp4c, my result is wrong

My task is to solve

3*y"+2*y'=x

y(0)=-2

y(1)=6

my matlab code:

dydt=@(x,y)[y(2); y(2)+x];

bc=@(ya,yb)[ya(1)+2; yb(1)-6];

yinit=@(x)[exp(-x); -exp(-x)];

solinit=bvpinit(linspace(0,1,20),yinit);

sol=bvp4c(dydt,bc,solinit);

plot(sol.x,sol.y(1,:))

Could you help me to find what wrong?

I think you want: dydt=@(x,y)[y(2); (x-2*y(2))/3];
