solution to homogeneous system of linear equations with coefficients over field $\mathbb{F}_2$    
   Solve the following homogeneous systems of linear equations with coefficients over field $\mathbb{F}_2$:
 x1+x2+x3+x4+x5+x6+x7 = 0
 x1=0
 x2+x3+x4 =0
 x5=0
I want to output on the sage following:
x1=x5=0
x6=x7
x2+x3+x4=0
I want to solve a general homogeneous systems with coefficients over field $\mathbb{F}_2$ and output same as above.
I hope that someone can help. Thanks!
