Eight times a number is the same as 30 less than 5 times the number. Find the number?
Charra [1.4K]

Answer:

x = -10

Step-by-step explanation:

>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
