Systems of linear equations: Systems of linear equations
Elementary operations on systems of linear equations
Solve the following system of equations with unknowns \(x\) and \(y\) via the row reduction method. \[ \lineqs{ 8 x-7 y &=& 0 \cr x-y &=& -4 \cr}\]
Enter the answer in the form \[ \lineqs{x=a\cr y=b\cr}\] or in the form \[x=a\land y=b\] with proper values of #a# and #b#.
You can enter the above system \[ \lineqs{ 8 x-7 y &=& 0 \cr x-y &=& -4 \cr}\] as a starting point for reduction to a solution or use herefore the following form \[ 8 x-7 y=0 \land x-y=-4 \]
