Identify the determinants for the given

Explanation:

The first determinant is that of the matrix of coefficients:

The second determinant is the same as the above but with the constants substituted for the x-coefficients.

The third determinant is the same as the first but with the constants substituted for the y-coefficients.

_____

The solution to the system of equations is then ...

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
