Question

8x÷4=100 What is the value of x in the equation?

Answer 1

x = 50

Explanation:

To answer this question, we have to isolate the x. To do this, we have to get rid of any other numbers around it by doing the inverse of the operation.

1)

• ÷ 4 = ×4 to both sides
• 8x ÷ 4 × 4 = 8x
• 100 × 4 = 400
• 8x = 400

2)

• 8x = ÷ 8 to both sides
• 8x ÷ 8 = x
• 400 ÷ 8 = 50
• x = 50

This means that x is 50!

To check our answer is correct we can substitute 50 to x in the question...

• (8 × 50) ÷ 4 = 100

It is correct!

Hope this helps, have a lovely day! :)

Answer 2

Solving 8x ÷ 4 = 100, we have:

2x = 100

x = 50

So the value of x is 50.
