Answer:

x = -3

y = 3

Explanation:

2x + 10y = 24

x = y - 6

plugin x = y - 6 into the first equation

2(y - 6) + 10y = 24

solve for y

2y - 12 + 10y = 24

12y = 36

y = 3

plug y back into x = y - 6

x = 3 - 6

x = -3

Answer:

(-3,3)

Explanation:

Substitute x for the first equation

2(y-6) + 10y= 24

2y-12+10y=24

12y=36

y=3

Now solve for x by plugging in 3

x = 3-6

x=-3
