Question

1. 2х + 4y = 26
3х - у = 4

2. 3x + 2y = 16
2x – Зу = 2​

Answer 1

Explanation:

1. 2x + 4y = 26

3x - y = 4 => y = 3x -4

2x + 4(3x - 4) = 26

2x + 12x - 16 = 26

14x = 42

x = 3

3(3) - y = 4

y = 5

2. 3x + 2y = 16

2x - 3y = 2

9x + 6y = 48

4x - 6y = 4

13x = 52

x = 4

3(4) + 2y = 16

2y = 4

y = 2
