x=4x=4

Explanation:

I'm assuming your problem is 5x=205x=20, because it looks like your trying to multiply 55 by a number but your number is missing, so I'm predicting that your question is 5x=205x=20.

In that case:

5x=205x=20

Divide by 55 from both sides to eliminate 55 on the LHSLHS.

(cancel5x)/cancel5=20/5

20-:5=4

The answer is x=4.

Explanation:

To solve one-variable equations like this one, you need to perform actions on both sides of the equation so that in the end, x is on one side of the=sign, and numbers are on the other.

In this case, we want to divide both sides of the equation by 5 in order to get x by itself, because to get from 5x to x, you need to divide by 5.

5x=20

5xcolor(red)(-:5)=20color(Red)(-:5)

cancel(5)x-:cancel(5) = 20-:5

x = 20-:5

x = 4
