3x – 2y = 2
7x + 3y = 43​

Answer 1

Answer:

4

Step-by-step explanation:

expressing the equations in terms of one variable  

3x – 2y = 2  

………[1]  

7x + 3y = 43  

………[2]  

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

14y + 14 = 129 – 9y

 

⇒ 23y = 115  

⇒ y = 5 ………[3]

 

by using [3] in [1]    

 

⇒ x = 4
