Ymorist [56]4 years ago
6 0

Answer:

The value of x is 7 and y is 14.

Step-by-step explanation:

The steps are :

- 3x + y =  - 7 -  -  - (1)

y = x + 7 -  -  - (2)

(2)→(1)

- 3x + (x + 7) =  - 7 \\  - 3x + x + 7 =  - 7 \\  - 2x =  - 14 \\ x = 7

substitute \: x = 7 \:  \: into \:  \: (2)

y = 7 + 7 \\ y = 14
