9(n+3)=7n-3

1) distribute 9 into (n+3)

9n+27=7n-3

2) subtract 7n on both sides

2n+27=-3

3) subtract 27 on both sides

2n=-30

4) divide by 2

n=-15

Okay so the relationship between points K and K' is that you subtract 4 from the x values and you add 6 to the y values.

1 - 4 = - 3

L ( - 3 , 3 ) ==> L' ( - 3 - 4 , 3 + 6 ) ==> L' ( - 7 , 9 )

The only answer option with L' as such is answer choice B.
