I think I posted right this time
I need the values of the variables in each equations.
You can take advantage of certain rules of matrix calculations, I will sum them up first, and explain.
Let A, B and C be m x n matrices, i.e. they all have the same number of rows (m) and number of columns (n).
We denote elements of the matrices by aij for the element on the ith row and the jth column of matrix A. The same notation applies to matrix B and C.
Then if
A + B = C
then
aij + bij = cij
for i=1 to m, and j=1 to n.
In the given case, m=2 and n=3, and so we end up with six equations, such as:
a11+b11=c11,....(1)
a12+b12=c12
....
a23+b23=c23......(6)
You will need to solve each of the six equations for the respective unknowns.
I will solve the first one as an example:
a11=a+2
b11=3a
c11=10
So equation (1) becomes:
a+2+3a=10
solve for a
a+3a+2=10
4a=8
a=2
You should be able to solve for the remaining variables.
