Question

500=100(x-1)

Someone tell me step by step ?
Last time it was explained by someone else I didn’t understand

Answer 1

6 = x (highly reccomend the explanation part)

Explanation:

What you need to do is "open" the paranthesis. So 100(x-1) is basically

(* =times)

500 = 100 * x + 100 * -1

Let's simplify again

500 = 100x + (-100)

500 = 100x - 100

Now we need to isolate "x", so we add 100 to each side (to remove the -100)

600 = 100x

Simply divide everything by the "x" modifer (which is 100)

6 = x

Answer 2

This a basic equation in which we have to attempt and solve for the value of 'x'. The basic thing to look out for this is we have to open the bracket (x - 1) by 100 i.e we are gonna to multiply (x - 1) by 100.

After simplification we do get,

`\implies\rm{500 = 100(x - 1)}`

`\implies\rm{500 = 100x - 100}`

`\implies\rm{500 + 100 = 100x}`

`\implies\rm{600 = 100x}`

`\implies\rm{ (600)/(100) = x}`

`\implies\rm{6 = x}`

`\implies\rm{x = 6}`

• Thus the value of x is 6.
