Question

Solve for x please help (show work!)

Answer 1

x = 1/2 or 0.5

Explanation:

8(-2x + 1) = 0

Distribute the 8 by multiplying 8 by what's inside of the parenthesis (-2x and 1)

8 * -2x = -16x

8 * 1 = 8

We now have

-16x + 8 = 0

Subtract 8 from both sides

-16x + 8 - 8 = 0 - 8

-16x = -8

Divide both sides by -16

-16x/-16 = -8/-16

x = 1/2

Answer 2

G I V E N :

8( -2x + 1 ) = 0

S O L U T I O N :

• 8( -2x + 1 ) = 0

Simplify the left hand side

• -16x + 8 = 0

Transposing -16x to the other side

• 8 = 16x

Cross multiplying we get

• x = 8/16

• x = ½

• x = 0.5

Hence the value of x is 0.5 or ½
