Answer:
x=1, y=2. (1, 2).
Step-by-step explanation:
x-3y=-5
-3x+7y=11
----------------
x=3y+(-5)
x=3y-5
-3(3y-5)+7y=11
-9y+15+7y=11
-2y=11-15
-2y=-4
2y=4
y=4/2
y=2
x-3(2)=-5
x-6=-5
x=-5+6
x=1

Answer:
x=3/4
Step-by-step explanation:
First, we must combine like terms and find the common denominator (which is 5):
12/5x-2x
12/5x-10/5x=2/5x
Then, we cross multiply
= 2x(10)=(3)(5)=20x=15
Then, we divide by 20 to get x:
x=15/20
and finally, we simplify the fraction
x=3/4
Answer:
No, because James has confused the hours of watching tv with the hours of reading.
Step-by-step explanation:
This is incorrect. According to the graph, what we have is a point on the line at (6, 10), which implies that a student who reads for 6 hours will watch tv for 10 hours.
It is very likely that James is confusing the hours of watching tv with the hours of reading.
