Can anybody explain substitution ?

Answer

Ok substitution would be like 9(3x+4)-2 something like than but for example you would multiply the 9 by the 3x and the 4..
. The number in front of the parenthesis which is 9 on that problem is what u multiply what's on the parenthesis so then it would be 27x+36-2 then do the rest so then you subtract 36 from both sides so it's now a negative 38 now because -36 -2 is -38 the divide by x which wouldn't look so cool because it would be a decimal
