Answer:
(3, -1)
Step-by-step explanation:
The easiest way to solve this system of equations is by elimination:
3x + y = 8
2x - y = 7
Add the two equations together:
(3x + 2x) + (y - y) = (8 + 7)
5x = 15
x = 3
Substitute x back into the equation:
2x - y = 7
2(3) - y = 7
6 - y = 7
- y = 1
y = -1
The fourth option, (3, -1)
Answer:
3x - 23 = 28
Step-by-step explanation:

Hope this helped have a great day/night!!!
Greetings! let’s solve this shall we?
So,
7x + 14 > -3x - 6
14 > -3x - 6 + 7x
14 > 4x - 6
20 > 4x
5 > x
