Solve for y x+2y=6. what's the answer

Solve for y

x+2y=6

Add (-x) to both sides:

x + 2y + (-x) = 6 + (-x)

Simplify:

2y = 6 - x

  Divide both sides by 2

2y/2 = (6-x) / 2

2y/2 = 6/2 - x/2

  y = 3 - x/2

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1
