anonymous · Answer

ans is (6,4)? correct?

abb0t · Answer

Substitute your x = 2y-2 for x in the second equation. and solve for y.

abb0t · Answer

Once you have your y, plug in that value back for the first equation to get your x.

anonymous · Answer

3(2y-2)-y=14?

anonymous · Answer

3(2y - 2) - y = 14
5y-6 = 14
y=4 => x=6
(6,4)

anonymous · Answer

how did you get 5y? it would be 6y

anonymous · Answer

yes but them you have a -y, so 5y

anonymous · Answer

oh

anonymous · Answer

6y -6 -y =14

anonymous · Answer

5y-6=14 i get that but what did you do after that?

anonymous · Answer

5y = 14+6
5y = 20
y=4
them from 3x - y = 14
3x - (4) = 14
3x = 18
x=6
so (6,4)

anonymous · Answer

oh ok thank you i get it:)
