Answer:
- y = -5/2x + 5
- y = 2x -1
- y = 24/11
- y = 4x + 4
Step-by-step explanation:
To solve for y, subtract the x-term and divide by the coefficient of y.
5x +2y = 10
2y = -5x +10
y = -5/2x + 5
__
2y -4x = -2
2y = 4x -2
y = 2x -1
__
7y +4y = 24
y = 24/11
We assume there is a typo, but cannot tell what it is. Use the same method as described and demonstrated for the other problems.
__
-2x +1/2y = 2
1/2y = 2x +2
y = 4x +4
Answer:
It is a solution of the ordered pair.
Step-by-step explanation:
The y intercept is (0,-2)

141,161
Step-by-step explanation:
Answer:
= 100 km
Step-by-step explanation:
Total length = 5/5
Covered length = 2/5
Remaining length = 5/5 - 2/5 = 3/5
If 3/5 = 60 km
What about 5/5 = ?
= 5/5 x 60 x 5/3 (reciprical)
= 60 x 5/3
= 300/3
= 100 km
Covered distance = 100 - 60 = 40 km
