Question

Class 10
2x+3y= 9
4x+6y =18​

Answer 1

Answer:

Step-by-step explanation:

Given the equation 2x+3y=9 and 4x-6y=18  

we have to solve using substitution method.

2x+3y=9

⇒ x=(9-3y)/2

4x-6y=18

4 (9-3y)/2-6y=18

⇒ 2(9-3y)-6y=18

⇒ 18-6y-6y=18

⇒ 18-12y=18

⇒ -12y=0

⇒ y=0

2x+3y=9

2x=9

x=9/2
