Question

If x = a, y = b is the solution of the equations x –y = 2 and x + y = 4, then the values of a and b are respectivel​

Answer 1

Answer:

a = 3 , b = 1

Step-by-step explanation:

x+y = 4

x-y = 2

2x = 6

x = 3

substitute x in anyone equation

x+y = 4

3+y = 4

y = 4-3

y = 1

hence a = 3 , b = 1
