Question

x=1,y=-1 is a solution of the system of linear equation 2x +5y=3 and x-3y=4​

Answer 1

Answer:

Correct question:

Prove that x=1,y=-1 is the solution of the system of linear equations;

2x+5y=-3 and x-3y=4.

Solution;

The given equations are;

2x + 5y = -3 ------(1) and

x - 3y = 4 ------(2)

The given point is:

x=1 , y=-1. ie, (1,-1)

If (1,-1) is the solution of the given system of linear equations, then it will satisfy the both equations simultaneously.

Let's check for eq-(1)

LHS = 2x + 5y

= 2(1) + 5(-1)

= 2 - 5

= -3

= RHS

Let's check for eq-(2)

LHS = x - 3y

= (1) - 3(-1)

= 1 + 3

= 4

= RHS

Since, the given coordinate (1,-1) satisfy both the equations, thus x=1,y=-1 is the solution of the given system of linear equations.
