Question

Solve the pair of linear equation x+2y=8 , x-3y=13​

Answer 1

Step-by-step explanation:

x+2y=8.............eq(1)

x-3y=13..............eq(2)

eq(1)-(2)

x+2y=8

x-3y=13

5y=-5

y=-1

sub in eq(1)

x+2(-1)=8

x=8+2

x=10

Hope it helps you

Answer 2

Answer:

x + 2y = 8

x- 3y =13       substract

------------------

5y = - 5

 y= -1

substitute the value of y in any equation

x- 3y = 13

x = 13 + 3y

  = 13 + 3 * -1

 = 13 -3

= 10

therefore x=10 and y= -1 ( answer)
