Question

Solve the following pair of linear equations by any suitable method x+y=5 2x-3y=5

Answer 1

Answer:

Step-by-step explanation:

Solving by elimination method

Multiplying the equation 1st by 3

(x+y=5)3

= 3x+3y=15

Eliminating the equation 3x+3y=15 by 2x-3y=5

3x+3y=15

2x-3y=5

___________

5x =20

x = 20/5

x=4

Put the value of x in equation 1

4+y=5

y = 5-4

y = 1

Now checking the equation

x+ y = 5

x= 4 , y = 1

4+1 =5

5=5

RHS = LHS

Our answer x = 4 and y = 1 is right
