# Let us solve the following simultaneous equations in two variables by the method of comparison:

2x – 3y = 8

Answer :

expressing the equations in terms of one variable

2x – 3y = 8

………[1]

⇒ 3x + 3y = 7x – 7y

⇒ 4x = 10y

………[2]

by comparing eq. [1] and eq. [2]

⇒ 8 + 3y = 5y

⇒ 2y = 8

⇒ y = 4 ………[3]

by using [3] in [1]

⇒ x = 10
