# How to use equation solutions returned by `solve`?

While obtaining the answer for A3 and A3 in a set of equations, the answer is in vector-format(??). I want to use these answer further on. How can I pick these values? Right now I just copy and paste the answer but that's not ideal.

IN:

```
eq1=-A3-A4*K*l+A3*cos(K*l)+A4*sin(K*l)+((qzc*l^2)/(2*K^2))==0
eq2=-A3*K^2*cos(K*l)-A4*K^2*sin(K*l)+(qzc/(K^2))==0
solve([eq1,eq2],A3,A4)
```

OUT:

```
[[A3 == 1/2*(2*K*l - (K^2*l^2 + 2)*sin(K*l))*qzc/(K^5*l*cos(K*l) - K^4*sin(K*l)), A4 == 1/2*((K^2*l^2 + 2)*cos(K*l) - 2)*qzc/(K^5*l*cos(K*l) - K^4*sin(K*l))]]
```
