Answer:

Step-by-step explanation:

move all the terms to the right so your equation will equal 0. then look for the common denominator. which in this case is 60 (5*4*3).

multiply all terms by 60 then simplify.

12(2x-3)-15(6-3x)+120-20(7x)=0

24x-36-90+45x+120-140x=0

combine like terms and then divide

-71x=6

x=-6/71

(do not forget parenthesis when simplifying they are very important when it comes to distributing the minus sign)

If 120 marks is 60% what is full marks

AveGali [126]

Let's say is "x", so, then "x" is the 100%, and we know that the 60% is 120, what the dickens is "x" anyway?

$\bf \begin{array}{ccll}
marks&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
x&100\\
120&60
\end{array}\implies \cfrac{x}{120}=\cfrac{100}{60}\implies x=\cfrac{120\cdot 100}{60}$
