PLEASE HELP WITH THESE 4 PROBLEMS

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
