Heres some free points if you take them please pass it on :)

For the equations below which statement is true ? -2x=14 6x=-42

If f(x) = x+8 and g(x) = 4x- 3, find (f+g)(x)

In the figure below, ∠dec ≅ ∠dce, ∠b ≅ ∠f, and segment df is congruent to segment bd. point c is the point of intersection between segment ag and segment bd, while point e is the point of intersection between segment ag and segment df. the figure shows a polygon comprised of three triangles, abc, dec, and gfe. prove δabc ≅ δgfe.
