Question

Perimeter is 25 solve for x

2x-8

2x+5

30-3x

Answer 1

The answers are
`(33)/(2) ,10\ and\ (5)/(3)` .

Explanation:

Given:

Perimeter is 25.

2x-8

2x+5

30-3x

Now, to solve for
`x.`

So, the first equation to solve:

`2x-8=25`

Adding both sides by 8 we get:

`2x=33`

Dividing both sides by 2 we get:

`x=(33)/(2)`

Then, the second equation to be solve:

`2x+5=25`

Subtracting both sides by 5 we get:

`2x=20`

Dividing both sides by 2 we get:

`x=10.`

And, the third equation to solve:

`30-3x=25`

Subtracting both sides by 30 we get:

`-3x=-5`

Dividing both sides by -3 we get:

`x=(5)/(3)`

Therefore, the answers are
`(33)/(2) ,10\ and\ (5)/(3)` .
