sum the forces in y, and the moment about point 1

define the point at which w1 acts as point 1, x=0
define the point at which w2 acts as point 2, x=35

Sum Fy=0

integral from 0 to 35 of [(w2-w1)/35in)x+w1]dx = 12000lbs


Sum M1=0

integral from 0 to 35 of x[(w2-w1)/35in)x+w1]dx - (14in)(12000lbs) = 0

I'll let you mess with the integration and solve for the two variables (or you can be crafty and replace the integrations with common shape area formulae)
