Solve the following equation for x: 6x-16=14
Ivenika [448]

To solve the equation for x, first, we add 16 from both sides of the equation:

\begin{gathered} 6x-16+16=14+16, \\ 6x=30. \end{gathered}

Now, we divide by 6:

\frac{6x}{6}=\frac{30}{6}.

Finally, we get that:

x=5.

Answer:

x=5.

What is the greatest common factors of 120 and 6
horrorfan [7]
If we want to know the greatest common factor, we should ask: is one of the numbers divisible by the other? if yes, then the smaller number will be the answer!

let's try:

\frac{120}{6} = \frac{60}{3} =20

so, yes!
6 is the greatest common factor of the two:)
