Question

x/2+2y/3=1 x-y/3=3 using substitution method​

Answer 1

Answer:

Step-by-step explanation:

To solve the following equation:

x/2 + 2y/3= 1     .... (1)  

x- y/3= 3             .... (2)

Multiply both the first equations by 6 and the second by 3, we get

3x + 4y = 6      .... (3)

3x - y = 9          .... (4)

Subtracting equation (4) from (3), we get

5y = -15   =>  y = 3

Put y = -3 in equation (4),

3x - (3) =9

=> 3x + 3 = 9

=> 3x = 6

=>   x = 2.

Hence x =2 and y = 3.
