Answer:

x = 2

Explanation:


(1)/(2) (x+12)=4x-1

Solve the brackets.


(x)/(2) +6=4x-1

Take 4x to the left side and take 6 to the right side.


(x)/(2)-4x=-1-6

Combine like terms.


(x)/(2) -(4x)/(1) =-7\\\\(x)/(2) -(8x)/(2) =-7\\\\(-7x)/(2) =(-7)/(1)

Use cross multiplication.

-7x = -7 × 2

-7x = -14

Divide both sides by -7.

x = 2
