Question

If x=a,y=b is the solution of the equations x-y=2 and x+y=10, then find the values of a and b

Answer 1

If x=a,y=b is the solution of the equations x-y=2 and x+y=10, then a=6 and b=4

Answer 2

Answer:

a=10,b=0

Step-by-step explanation:

x=a y=b

x-y=2 .....(1)

x+y=10.....(2)

putting the value of X and Y in equation (1) & (2)

Therefore, a-b=2

therefore, a=b+2 ......(3)

a+b=10.....(4)

putting the value of a in equation (4)

therefore, b+2+b=2

2b+2=2

2b =2-2

2b=0

b=0

putting the value of b equation 4

a+0=10

a=10
