Question

check out whether the lines representing the following pairs of linear equations are intersecting lines or parallel lines or coincident. if the lines are intersecting slove the equation by elimination method. also write conditions for all the equation A) 3/2x+2y=5, 2x-3y=7​

Answer 1

Answer:

Systems of linear equations can be used to solve resource allocation prob-

lems in business and economics (see Problems 73 and 76 in Section 4.3 on

production schedules for boats and leases for airplanes). Such systems can

involve many equations in many variables. So after reviewing methods for

solving two linear equations in two variables, we use matrices and matrix

operations to develop procedures that are suitable for solving linear systems of

any size. We also discuss Wassily Leontief’s Nobel prizewinning application

of matrices to economic planning for industrialized countries.
