# Unable to make sense of Maxima expression

Hey everybody,

I'm trying to do some symbolic calculations. When trying to solve the following equation set for `v_0`

, `v_1`

, `w_0`

, and `w_1`

, I get "TypeError: Unable to make sense of Maxima expression".

The equations are added below:

```
v_0 == 1/6*(2*(s0_0 + s1_0 + s2_0)*t0_1 + 2*(s0_0 + s1_0 + s2_0)*t1_1 -

And the exact error is:

```
