X:(4900:70)=80

X:70=80

X=70 x 80

X= 5600

X x 20 = 240:3

Х х 20= 80

Х= 80 : 20

Х = 4

Answer 2

I'm sorry, but the statement you provided is not clear. It seems to be a mathematical equation, but the notation is unusual, and there might be some missing information. Could you please provide more context or clarify the notation used in the equation?

For example, "X : (4900 : 70) = 80" is not a standard mathematical expression, and "X×20 = 240 : 3" is also unclear without knowing the intended meaning of ":" and "×" in this context.

If you can provide more details or explain the notation used, I'll be happy to help you understand and solve the equation.
