9x - y = -7 is the answer
That’s hard lol but it’s angle 5 to the power of 7.t!$/&:
4 1/8-2 3/4= 4 1/8 - 2 6/8= 1 3/8
2 3/5 + 1 5/6 = 2 18/30 + 1 25/30= 3 43/30 = 4 13/30
8 9/12 + 2 3/8= 8 18/24 + 2 9/24= 10 27/24 = 11 3/24= 11 1/8
3 1/3 - 1 1/2= 3 2/6 - 1 3/6 = 2 8/6 - 1 3/6= 1 5/6
Answer:
x=2, y=1
x=-2, y = -1
Step-by-step explanation:
x - 2y = 0
x = 2y
x² - y² = 3
(2y)² - y² = 3
3y² = 3
y² = 1
y = 1 or y = - 1
x = 2 or x = -2
