Best ResponseYou've already chosen the best response.1\[\huge\rm f(\color{red}{g(x)})\textrm {is same as }f(\color{reD}{10x6})\] so substitute x for 10x6 into f(x) function

Best ResponseYou've already chosen the best response.0so it would be x = 3/5?

Best ResponseYou've already chosen the best response.1no f(g(x)) means you should substitute x for g(x) function which is 10x6 so in other words replace x by 10x6 x=10x6

Best ResponseYou've already chosen the best response.1\[\huge\rm f(\color{reD}{10x6})=4\color{reD}{x}+7\] replace the x by 10x6

Best ResponseYou've already chosen the best response.1\[\huge\rm f(\color{reD}{10x6})=4\color{reD}{(10x6)}+7\] distribute parentheses by 4 and then combine `like` terms

Best ResponseYou've already chosen the best response.0so then f = 4(20x  12) + 7 ??

Best ResponseYou've already chosen the best response.1multiply both terms in the parentheses by outside number \[\huge\rm a(b+c)=a \times b+a \times c\] like this

Best ResponseYou've already chosen the best response.0OHH so it's 40x + 24

Best ResponseYou've already chosen the best response.1\[\huge\rm \color{reD}{4(10x6)}+7\] \[\huge\rm \color{reD}{40x+24}+7\] red part equal to 4x+24 right now combine like terms
