Answer:
<h2>58.561</h2>
Step-by-step explanation:
The question is not properly formatted, here is a correct format
0.123+0.09 + 0.098 + 1.25 + 57
This is an addition problem, given the numbers to be added
0.123+0.09 + 0.098 + 1.25 + 57
58.561
the answer to the sum of the numbers 0.123+0.09 + 0.098 + 1.25 + 57 is
58.561
All of the z coefficients are zero. This means that the matrix will have a column full of zeroes:

And every time a matrix has a row/column full of zeroes, its determinant is zero.
Combine the numbers with the same variable
18a + 9a = 27a
24b + 14b = 38b
your answer is 27a +38b
