Simplify the equation.

Then subtract
from all sides.

Simplify again.

Multiply all sides by
.

Simplify again.

Divide all sides by 

Simplify again.

1) We know that <DAB and <BAC are supplementary angles according to the exterior angle theorem, so we set up the following equation and solve:
105+x=180
x=75
2) Since we have the angles for <BAC and <ABC and a triangle has its total angles added up to 180, we can set up an equation to find <ABC and solve:
75+35+x=180
110+x=180
x=70
So the m<ABC is 70 degrees.
