whats x in the expression 5x=20
5x = 20
Divide both sides by 5 to isolate x.
5x/5 = 20/5
x = ?
Divide both sides of the equation by 4 to get the answer.
x = 4 . It has to be 4 if the equation is to be valid.
5x=20
This means that 5 times some number is 20. To find that number, divide both sides of the equation by 5.
5x = 20
x = 20/5
x = 4
whoops. Ms Sue is right, of course. I meant "divide both sides by 5" and that is what I did.
To find the value of x in the expression 5x = 20, you can solve for x by performing an operation called "isolating the variable."
Here's how you can do it step by step:
Step 1: Divide both sides of the equation by 5. This is done to cancel out the coefficient of x (which is 5) and isolate the variable x.
5x / 5 = 20 / 5
x = 4
Step 2: In the equation, x = 4, you have found that x equals 4. Therefore, the value of x in the expression 5x = 20 is 4.
