Question

If x = a, y = b is the solution of the pair of equation x-y=2 and x+y=4 then what wil be value of a and b?​

Answer 1

Step-by-step explanation:

x-y=2

x+y=4

2x=6,x=3

a=3

y=1 so b=1

Answer 2

Answer:

a = 3

b = 1

Step-by-step explanation:

Adding equations

• x + y = 4
• x - y = 2

_______________

• 2x = 6

• x = 6/2

• x = 3

Substituting x = 3 in x + y = 4

=> 3 + y = 4

=> y = 4 - 3 = 1

Therefore the value of a is 3 and b is 1
