Answer: The solution is,
x = 2, y = 7
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
