Finding the inverse of a matrix to solve a 2x2 system of linear equation

System of eq. -2x+6y=10

3x-8y=-12

A. Suppose the coefficient matrix is A=[-2 6]

[ 3 -8] both in 1 bracket

Find A^1 and use it to write solution matrix [x]

[y]as a product of 2 matrices.

[x]

[y]= [] x []

B. find the solution of the system, write the answer in simplest form

x= y-
