Question

Eight times a number is the same as 30 less than 5 times the number. Find the number?

Answer 1

Answer:

the number = -10

Step-by-step explanation:

1. to find the number, make it x. then, make an equation with it.

  8x = 5x - 30

2. then, you just solve the equation

  - subtract 5x from both sides

     3x = -30

  - divide by 3

     x = -10

hopefully that makes sense! :)

Answer 2

Answer:

x = -10

Step-by-step explanation:

We just have to translate the problem correctly

>8 times a number is the same

this tells me that

$8x = ...$

>as 30 less than 5 times the number.

$... = 5x - 30$

Now set them equal to eachother

$8x = 5x - 30$

Now isolate the variable x

$8x - 5x = 5x - 5x - 30\\3x = -30\\x = \frac{-30}{3} = -10$
