Jamir Reed · Answer 1

2x + 6y = - 6

Factor out the common term 2

2 (x+3y) = - 6

2 Divide both sides by 2

x+3y=-6/2

3 Simplify 6/2 to 3

x+3y=-3

4 Subtract 3y from both sides

x=-3-3y

Julie Harvey · Answer 2

2x + 6y = - 6

2x + 5y = - 2

y = - 4

2x + 6y = - 6

2x + 6 (-4) = - 6

2x - 24 = - 6

+ 24 + 24

2x = 30

2 2

x = 15

(x, y) = (15, - 4)
