Question

Solve: X+y=5 and 2x-3y=4

Answer 1

Answer:

$x + y = 5 = = = = > 1$

$2x - 3y = 4 \: = = = > 2$

$1 \times 2 = = = > 2x + 2y = 10$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 2x - 3y = 4$

Eliminating 2x,

$y = \frac{6}{5}$

Then

$x = \frac{19}{5}$

Answer 2

Answer:

$x + y = 5....(1) \\ 2x - 3y = 4....(2) \\ 1 \times 2 = > 2x + 2y = 10...(3) \\ (3) - (2) = 5y = 6 \\ y = \frac{6}{5} \\ then \\ x + \frac{6}{5} = 5 \\ x = 5 - \frac{6}{5} \\ x = \frac{25 - 6}{5} \\ x = \frac{19}{5} \\ thank \: you$
