system%28x%2By=1%2C%0D%0A+2x%2B5y=4%29

If you're doing it by the augmented matrix method (Gauss-Jordan method),

%28matrix%282%2C4%2C%0D%0A%0D%0A1%2C1%2C%22%7C%22%2C1%2C%0D%0A2%2C5%2C%22%7C%22%2C4%29%29

If you're doing it by the AX=B matrix method and multiplying
by the inverse:

%28matrix%282%2C2%2C1%2C1%2C2%2C5%29%29·%28matrix%282%2C1%2Cx%2Cy%29%29 = %28matrix%282%2C1%2C1%2C4%29%29
