Solve l=14j+3k for j.
Ganezh [65]
L = 14j + 3k
l - 3k = 14j
(l - 3k) / 14 = j
j = (l - 3k) / 14 (Flipped sides for aesthetics. I like having the thing I solve for on left, but that is completely optional)

Triangle PQR is dilated by a scale factor of 1.5 to form triangle P′Q′R′. This triangle is then dilated by a scale factor of 2 t
Lynna [10]
If you want to make it easier, just skip it and dilate by 3 instead of by 1.5 and then by 2. The only reason I can instantly assume it's D, it's because on vertex P, (3, -4) is (9,-12), the only answer with +9.
