Write as a Vector Equality 7x-9y=-4 , 7x+6y=11

Problem

{[7*x−9*y=−4],[7*x+6*y=11])

Solution

1. Identify the coefficients of the variables x and y from each equation to form the column vectors.

2. Express the system as a linear combination of the variable x multiplied by its coefficient vector and the variable y multiplied by its coefficient vector.

3. Equate this linear combination to the vector formed by the constants on the right side of the equations.

Final Answer

x*[[7],[7]]+y*[[−9],[6]]=[[−4],[11]]
