Q. 5 B4.6( 9 Votes )

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
