Q1 of 71 Page 58

Solve the following pairs of linear equations by the method of substitution:

2x + 3y = 5, 2x + 3y = 7

2x + 3y = 5

⇒ 2x = 5–3y


⇒ …[1]


By substituting eq[1] in 2x + 3y = 7



⇒ 5–3y + 3y = 7


⇒ 5 = 7


it is not true


we got this independent of any variable and it is a false statement, no real solution exists to these linear pair of equations.
