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

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
