You have to estimate the final result, so you take the 3 significant digits and round the number. As de fourth digit is 4 you have to estimate the result taking the 3 digit as it is. So, the estimate result is 0,177.
I’m pretty sure you would have to make them equal 1. 3x -10=7x+14 2. Add 10 to both sides 3. 3x=7x+24 4. Subtract the variable ( 7x ) from both sides 5. -4x=24 6. Divide -4/24 I hope I did it right let me know if any errors
