Question

Solve by elimination method 2x+3y=23 and 4x-y=19

Answer 1

The answer should be 27/7

Answer 2

Step-by-step explanation:

2x+3y=23 --(1)

4x-y=19 --(2)

multiply equ. (1)By 4 and equ. (2) by 2

8x+12y=92

8x-2y=38

- + -

____________

14y=54

$y = \frac{54}{14} = \frac{27}{7}$

putting value of y in equ. (1)

$2x + 3 \times \frac{27}{7} = 23 \\ = > 2x + \frac{81}{7} = 23 \\ = > 2x = 23 - \frac{81}{7} \\ = > 2x = \frac{161 - 81}{7} \\ = > 2x = \frac{80}{7} \\ = > x = \frac{80}{7 \times 2} \\ = > x = \frac{40}{7}$

hope this helps.
