Question

Eleven more than four times a number equal the number less 7 find the number

Answer 1

For this case we have to:

x: Let the variable representing the unknown number

We algebraically rewrite the given expression:

Eleven more than four times a number, is represented as:

`11 + 4x`

The number less 7, is represented as:

`x-7`

Thus, the expression is:

`11 + 4x = x-7\\11 + 4x-x = -7\\11 + 3x = -7\\3x = -7-11`

Equal signs are added and the same sign is placed:

`3x = -18\\x = - \frac {18} {3}\\x = -6`

So, the unknown number is -6

Answer:

`x = -6`
