Question

What solves 4 + 1/5x = -1 ?

Answer 1

Answer:
`x=-25`

Explanation:

For this exercise it is necessary to remember the multiplication of signs:

`(+)(+)+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-`

Then, having the following equation provided in the exercise:

`4 + (1)/(5)x = -1`

You need to solve for the variable "x" in order to find its value.

To solve the equation, you can follow the steps shown below:

Step 1: You need to subtract 4 from both sides of the equation. Then:

`4 + (1)/(5)x-(4) = -1-(4)\\\\ (1)/(5)x=-1-4\\\\ (1)/(5)x=-5`

Step 2: This is the final step. You must multiply both sides of the equation by 5 in order to find the value of the variable "x".

Then, you get the following result:

`(5)( (1)/(5)x)=(-5)(5)\\\\x=-25`
