2x +2x +1 =13 + x
4x - x = 13 - 1
3x = 12
x=12/3
x=4
Checking, 2*4+2*4+1 =17
13+4=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
