Question

What is 7+8x=0?Can someone answer this for me please

Answer 1

The expression we have is:

`7+8x=0`

And we need to solve to find the value of x.

Step 1. To solve for x we need to leave the term that contains x alone on one side of the equation. For that reason we will need to subtract 7 to both sides of the equation:

`7-7+8x=0-7`

And as you can see 7-7 on the left side will be 0, so we will be left only with 8x:

`8x=0-7`

and on the right side, 0-7 is equal to -7:

`8x=-7`

Step 2. Now we need to divide both sides of the equation by 8 in order to solve for x:

`(8x)/(8)=-(7)/(8)`

8/8 on the right side, is equal to 1, so we will be left with x:

`x=-(7)/(8)`

And this way we have found the value of x.

Answer:

`x=-(7)/(8)`
