Question

13 + 2y = 9х
Зу = 7х​

Answer 1

Answer:X=3 and y=7

Step-by-step explanation:

Answer 2

Solution -

13 + 2y = 9x

3y = 7x

↬13 + 2y = 9x

↬ 13 = 9x - 2y

↬ 3y = 7x

↬ 0 = 7x - 3y

[9x - 2y = 13] × 3

[7x - 3y = 0] × 2

27x - 6y = 39

14x - 6y = 0

- + -

___________

13x = 39

___________

13x = 39

x = 3

Substitute x = 3 in 3y = 7x

3y = 7x

3y = 7 × 3

y = 7

(x, y) = (3, 7)
