Question

Solve the equation below for x.
-1/2 (3x-4)=11

Answer 1

x= −6

Explanation:

you are supposed to isolate the variable by dividing both sides by the factor that do not contain the variable

Answer 2

C 6

EXPLANATION

The given equation is

`- (1)/(2) (3x - 4) = 11`

Multiply through by -2 to get:

`- (1)/(2) * - 2(3x - 4) = 11 * - 2`

`3x - 4 = - 22`

Add 4 to both sides of the equation:

`3x = - 22 + 4`

`3x = - 18`

Divide both sides by 3.

`x= - (18)/(3)`

This simplifies to

`x = - 6`

The correct answer is C
