Question

2. If x = a, y = b is the solution of the equations x + y = 5 and 2x – 3y = 4, then the values of a and b are respectively *​

Answer 1

Explanation:

Given pair of linear equations-

x−y=2 (1)

x+y=4 (2)

Adding equation (1) and (2), we have

(x−y)+(x+y)=2+4

x−y+x+y=6

2x=6

⇒x= 2/6 =3

Substituting the value of x in equation (1), we have

3−y=2

⇒y=3−2=1

Hence the values of a and b are 1 and 2 respectively.
