Question

Five less than eight times a number is equal to -1

Answer 1

The algebraic expression is:
`8x-5=-1`

the number is:
`\mathbf{x=(1)/(2)}`

Explanation:

Translating "Five less than eight times a number is equal to -1" into algebraic expression

Let the number = x

`8x-5=-1`

Now solving the expression to find value of x

`8x-5=-1\\Add\:5\:on\:both\:sides\\8x-5+5=-1+5\\8x=4\\x=(4)/(8)\\x=(1)/(2)`

So, the number is:
`\mathbf{x=(1)/(2)}`
