Question

find the solution of the following pair of linear equation, x+y=1,x-y=4

​

Answer 1

Answer:

X = 5/2

Y = -3/2

Step-by-step explanation:

Answer 2

Add both the equations

x + y = 1

× - y = 4

_______

2x = 5

x = 5/2

Put the value of x in any one of the equation

5/2 + y = 1

y = 1 - 5/2

y = -3/2

Hence the values of x and y are 5/2 and -3/2
