2x +2x +1 =13 + x

4x - x = 13 - 1

3x = 12

x=12/3

x=4

Checking, 2*4+2*4+1 =17

Answer:

Step-by-step explanation:

2x + 2x + 1 = 13 + x

To find the value of x, isolate 'x'

Step1: Subtract x from both sides

2x + 2x - x + 1 = 13

Step 2: Subtract 1 from both sides

2x + 2x - x  = 13 - 1

Step3: Combine like terms

       3x   = 12

Step 3: Divide both sides by 3

          x = 12/3

x = 4
