Say that the

height= 3x+2

base= 2

Area of a triangle equals 1/2 base times height

so...

(1/2) of the base is 1

and 1 times the height (3x+2) is 3x+2

Since the area equals 3x+2 and 85 you can set those numbers equal to each other to solve for x

3x+2=85

See if you can solve for x from this point

Just ask if you need any more help :-)
