Hi, is this right?

If \(\displaystyle x_1 = 30 \mu + \sum_j B_j + \sum_j(xB)_{1j} = y_1 \)

and

\(\displaystyle x_2 = 30 \mu + x_2 + \sum_j B_j + \sum_j(xB)_{2j} = y_2 \)

then is \(\displaystyle x_1 - x_2 = - x_2 + (y_1 - y_2) \)

is that right?

coz im confused about how to minus the summations:

\(\displaystyle \sum_j(xB)_{1j} - \sum_j(xB)_{2j} \)

can someone please help me out

oh and j goes from 1..3
