Solve for x and y: 4x - 3y = 8, 6x - y = 29/3

Answer»

The given system of equation is: 

4x - 3y = 8 ……(i) 

6x - y = 29/ 3 ……(ii) 

On multiplying (ii) by 3, we get: 

18x – 3y = 29 ….(iii) 

On subtracting (iii) from (i) we get: 

-14x = -21 

x = 21/14 = 3/2 

Now, substituting the value of x = 3/2 in (i), we get:

4 × 3/2 – 3y = 8 

⇒6 – 3y = 8 

⇒3y = 6 – 8 = -2 

y = −2/ 3 

Hence, the solution x = 3/2 and y = −2/3 .
