What is 4•(5-2)+4-6 to the 2nd power•10

With this question! what is process of elimination? ? p. s. my brothers acc got banned so add his new one @ yamauchiyamyam17

Kapil needed to buy a long wooden beam. he went to two sawmills that each charge an initial fee plus an additional fee for each meter of wood. the following equation gives the price (in dollars) of a wooden beam from the first sawmill as a function of its length (in meters). p = 5+20xp=5+20x

What is the answer to this question? i'm a bit stumped. also how do i do it? 5(x - 4) = 2(x + 5)
