Question

Please help me on this.

Answer 1

y = 2

Explanation:

2x + y = 14 + y

2x = 14

x = 7

5x - y = x + 13y

4x = 14y

4(7) = 14y

28 = 14y

2 = y

Answer 2

Let's go:

`\2x + y = 14 + y \\\ 2x = 14 \\\ x = 7 \\\ (2x + y)/(14 + y) = (5x - y)/(x + 13y)`

Changing x for 7:

`(2.7 + y)/(14 + y) = (5.7 - y)/(7 + 13y) \\\\ (14 + y)/(14 + y) = (35 - y)/(7 + 13y) \\\\ (35 - y)/(7 + 13y) = 1 \\\\ 35 - y = 7 + 13y \\\ 14y = 28 \\\ y = 2`

I hope I helped you.
