Given equations are,

\

\"\".

\

\"\".

\

Write the augmented matrix,

\

Place the coefficients of the equations and the constant terms in to matrix.

\

\"\" \"\"

\

Notice that the first element in the second row is 1.multiply the first (\"\") row by \"\"

\

\"\"          (The result is placed in row 1)\"\"

\

\

To make the first element in the second (\"\") row a 0, multiply the first (\"\") row by 8 and added the result to row 2 (\"\").

\

\"\"   (The result is placed in row 2)

\

Therefore,solution of the two equations is infinite.

\

\"\"

\

The solution is  infinite.
