Answer:


(1)/(2) (2x + 1) = 3


x + (1)/(2) = 3


x = 3 - (1)/(2)


x = (6 - 1)/(2)


x = (5)/(2)

To solve for x, you need to isolate/get the variable "x" by itself in the equation:


(1)/(2)(2x + 1)=3 Multiply the reciprocal of 1/2 on both sides, which is 2/1 or 2


2((1)/(2) )(2x+1)=2(3)

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


(2x)/(2) =(5)/(2)


x=(5)/(2)
