Write as a Vector Equality -9y+4x-20=0 , -7y+16x-80=0

Problem

−9*y+4*x−20=0,−7*y+16*x−80=0

Solution

1. Rearrange the equations into the standard form a*x+b*y=c by moving the constant terms to the right side of the equals sign.

4*x−9*y=20

16*x−7*y=80

2. Identify the coefficients of the variables x and y to form the coefficient matrix A

A=([4,−9],[16,−7])

3. Define the vector of variables v and the vector of constants b

v=([x],[y])

b=([20],[80])

4. Construct the vector equality by expressing the system in the form A*v=b

([4,−9],[16,−7])*([x],[y])=([20],[80])

Final Answer

([4,−9],[16,−7])*([x],[y])=([20],[80])
