Hi I am marcoleongk89 , today I am going to help you solve the equation


I am a form2 student too

2.5/2.5+x = 3.5/14

35 = 3.5(2.5+x)

35 = 8.75 +3.5x

26.25 = 3.5x

x = 7.5
參考: You can buy a book call The Essential Of school Algebra,there are many examples inside it

I think your question should be 2.5/(2.5+x) = 3.5/14
2.5/(2.5+x)=1/4
2.5*4=2.5+x
10=2.5+x
x=7.5
參考: ME
