I need help with both finding value of x​

Micah solves a linear equation and concludes that x = 0 is the solution. his work is shown below. (1 – 3x) = 4(– + 2) 0 = x which statement is true about micah’s solution?

Express in the simplest form: (x^2+9x+14/x^2-49) / (3x+6/x^2+x-56)

Two angles are complementary. the large angle is 36 more than the smaller angle. what is the measure of the large angle?
