Help please and thanks

Ily begins solving the equation 4(x – 1) – x = 3(x + 5) – 11. her work is shown below. 4(x – 1) – x = 3(x + 5) – 11 4x – 4 – x = 3x + 15 – 11 3x – 4 = 3x + 4 how can her partial solution be interpreted?

Identify the initial amount a and the growth factor b in the exponential function. a(x)=680*4.3^x

Factor the polynomial by its greatest common monomial factor.
