$x = 1$ , $y = 1$

Step 1

Find the $A X = B$ from the system of equations.

Step 2

The matrix must be a square matrix to find the inverse.

Inverse matrix cannot be found

Step 3

Left multiply both sides of the matrix equation by the inverse matrix.

Step 4

Any matrix multiplied by its inverse is equal to $1$ all the time. $A \cdot A^{- 1} = 1$ .

$[\begin{array}{c} x \\ y \end{array}] = I n v e r s e$ matrix cannot be $f o u n d \cdot [\begin{array}{c} 1 \\ 1 \end{array}]$

$[\begin{array}{c} I n^{4} v e^{3} r^{2} s m a^{2} t^{2} i x c o^{2} b f u d \\ I n^{4} v e^{3} r^{2} s m a^{2} t^{2} i x c o^{2} b f u d \end{array}]$

Step 6

Simplify the left and right side.

$[\begin{array}{c} x \\ y \end{array}] = [\begin{array}{c} I n^{4} v e^{3} r^{2} s m a^{2} t^{2} i x c o^{2} b f u d \\ I n^{4} v e^{3} r^{2} s m a^{2} t^{2} i x c o^{2} b f u d \end{array}]$

Step 7

Find the solution.

$x = I n^{4} v e^{3} r^{2} s m a^{2} t^{2} i x c o^{2} b f u d$

$y = I n^{4} v e^{3} r^{2} s m a^{2} t^{2} i x c o^{2} b f u d$
