Answer:
1
Step-by-step explanation:
There can be 0, 1 or infinitely many solutions. 0 if they are parallel and are different lines, 1 if the slopes are different, and infinitely many if they are the same line.
2x - 4y = 8
x + y = 7
Change to y = mx + b
y = (1/2)x - 2
y = -x + 7
The slopes are different so there is 1 solution.

Answer:
- 5
Step-by-step explanation:
Given
x² - y² ← substitute x = 2 and x = - 3 into the expression
= 2² - (- 3)²
= 4 - 9
= - 5
