Answer:

x=3

Step-by-step explanation:

14=7(2x-4)

14/7=2x-4

2=2x-4

2x=2+4

2x=6

x=6/2

x=3

------------

14=7(2x-4)

14=14x-28

14x=14+28

14x=42

x=42/14

x=3

$14=7(2x-4)\\2=2x-4\\2x=6\\x=3\\\\14=7(2x-4)\\14=14x-28\\14x=42\\x=3$

I prefer the first method, because I don't do unnecessary multiplication and therefore operate on smaller numbers.

2470.28277045 To 3 decimal places

To run the these figures to 3 decimal places

you need to count from the digit after the decimal point until you reach the 3rd number which is 2

so now the answer is 2470.283

This is because the decimal point lies between 2 and 7 and since 7 is great than 5 we add 1 to the 2 making it 3
