First we have to isolate the varible

-2/5x-2=18
+2 +2

-2/5x=20

then divide both sides by -2/5 to get x completely by itself

-2/5x=20
------- ---
-2/5 -2/5

x=-50

Area of triangle = 1/2 x base x height

so old triangle we have 1/2 x b x h = 48

new triangle has base 3 times as long and height is half as long
so we would get:

1/2 x (3B) x (1/2H) = area

rewrite as 1/2 x 3/2 x b x H = area

divide by original are os 1/2 x b x h and you end up with 3/2

so new area = 3/2 x old area

new area = 3/2 * 48 = 72 square inches
