Question

How do you solve `2x + 5 = 17`?

Answer 1

`x = 6`

Explanation:

This is a question having to do with basic algebra:

Step 1: Isolate the variable. Subtract `5` from both sides:

`2x + 5 - 5 = 17 - 5`

`2x = 12`

Step 2: Solve. Divide both sides by `2`

`(2x)/2 = 12/2`

`x = 6`

Therefore,

`x = 6`

Answer 2

Subtract 2 from both sides
`2x+cancel5-cancel5=17-5`
You get
`2x=12`
Divide 2 from both sides
`(cancel2 x)/cancel2=cancel12^6/cancel2^1`
You get
`x=6`
Check:
`2xx6+5=17`
`12+5=17`
`17=17`
