Question

Step by step explanation

Answer 1

`\huge\boxed{\tt{x = -5 , y = 2}}`

Explanation:

x = y - 7 ---------------------(1)

-y - 2x = 8 --------------------(2)

Put Equation (1) into (2)

- y - 2 ( y-7 ) = 8

-y - 2y + 14 = 8

-3y = 8 - 14

-3y = -6

Divide -3 to both sides

y = -6 / -3

y = 2

Put y = 2 in (1)

x = 2 - 7

x = -5

So,

x = -5 , y = 2

`\rule[225]{225}{2}`

Hope this helped!
