Write as a Vector Equality 4x+2y=9 , 7x+5y=-1

Problem

4*x+2*y=9,7*x+5*y=−1

Solution

1. Identify the coefficients of the variables x and y on the left side of the equations to form the coefficient matrix.

2. Define the variable vector containing the unknowns x and y

3. Identify the constants on the right side of the equations to form the constant vector.

4. Express the system as a single vector equation by multiplying the coefficient matrix by the variable vector and setting it equal to the constant vector.

Final Answer

([4,2],[7,5])*([x],[y])=([9],[−1])
