Question

solve this equation by elimination method


2x+3y=7
3x-2y=6


​

Answer 1

Answer:

x= 7/2 and y = 9/13

Step-by-step explanation:

you need to have one common term, so multiply the 2 equations by 3 and 2 respectively.

the 2 new equations are

6x+9y=21 and 6x-4y=12

after subtracting you will get y = 9/13

substitute this value in any previous equation =

6x + 9*9/13 = 21

6x + 81/13 = 21

6x = 21 -81/13

6x = 21

x= 21/6 = 7/2.

therefore, x= 7/2 and y= 9/13

Answer 2

Basically it is a way through the help of which we can eliminate one variable of a simultaneous equation to get the answer.
