Question

Решите функцию:

4x+3у=2

5x-2y=3

Answer 1

2Y = 5X - 3 
Y = 2.5X - 1.5 
------------------
4X + 3Y = 2 
4X + 3*( 2,5X - 1,5) = 2 
4X + 7,5X - 4,5 = 2 
11,5X = 6,5 
X = 13/2 : 23/2 = 13/23 
--------------------
Y = 2.5X - 1,5 
Y = 5/2 * 13/23 - 3/2 = 65/46 - 69/46 = ( - 4/46) = ( - 2/23 )
