Answer:
The solution of the given system is (5,12).
Step-by-step explanation:
Here, the given system of equations is,
3x + 2y = 39 -------(1),
5x - y = 13 ---------(2),
Equation (1) + 2 × Equation (2),
We get,
3x + 10 x = 39 + 26
13x = 65
⇒ x = 5
From equation (1),
3(5) + 2y = 39,
15 + 2y = 39
2y = 39 - 15
2y = 24
⇒ y = 12,
Hence, the solution of the given system is (5,12).
