Question

Solve for x. 2x + 1 = 7 O X= 4 O x = 3 O X = 12 O X = 16

Answer 1

To answer this question, we need to isolate x. For this, we can proceed as follows:

1. Subtract 1 from both sides of the equation:

`2x+1-1=7-1\Rightarrow2x=6`

2. Divide by two to both sides of the equation:

`(2x)/(2)=(6)/(2)\Rightarrow x=3`

Therefore, the value for x = 3. We can check this result, if we substitute this value in the original euq
