Answer:
[tex] \frac{1}{2} (2x + 1) = 3[/tex]
[tex]x + \frac{1}{2} = 3[/tex]
[tex]x = 3 - \frac{1}{2} [/tex]
[tex]x = \frac{6 - 1}{2} [/tex]
[tex]x = \frac{5}{2} [/tex]
To solve for x, you need to isolate/get the variable "x" by itself in the equation:
[tex]\frac{1}{2}(2x + 1)=3[/tex] Multiply the reciprocal of 1/2 on both sides, which is 2/1 or 2
[tex]2(\frac{1}{2} )(2x+1)=2(3)[/tex]
2x + 1 = 6 Subtract 1 on both sides
2x + 1 - 1 = 6 - 1
2x = 5 Divide 2 on both sides to get "x" by itself
[tex]\frac{2x}{2} =\frac{5}{2}[/tex]
[tex]x=\frac{5}{2}[/tex]
