What is the value of the unknown side, x, correct to 2 decimal places?​

The solution is,

x = 2, y = 7

Step-by-step explanation:

Given system of equations,

6x + 3y = 33  (1)

4x + y = 15 (2),

Equation (1) - 3 × equation (2),

We get,

6x - 12x = 33 - 45

-6x = - 12

⇒ x = 2,

Substituting this value in equation (2),

4(2) + y = 15

8 + y = 15

⇒ y = 7,

Hence, the solution of the given system of equation is,

x = 2, y = 7
