Write as a Vector Equality -0.2x-0.7y=0.21 , 0.9x+0.8y=0.23

Problem

{[−0.2*x−0.7*y=0.21],[0.9*x+0.8*y=0.23])

Solution

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

2. Express the system as a linear combination of these column vectors, where x and y act as scalars.

3. Equate the sum of the scaled vectors to the vector containing the constants from the right-hand side of the equations.

Final Answer

x*[[−0.2],[0.9]]+y*[[−0.7],[0.8]]=[[0.21],[0.23]]
