Solve 18=-2(2x-1)

Evaluate

18 = - 2 (2 x - 1)

Swap the sides of the equation

- 2 (2 x - 1) = 18

Change the sign

2 (2 x - 1) = - 18

Divide both sides

\frac{2 ( 2 x - 1 )}{2} = \frac{- 18}{2}

Divide the numbers

2 x - 1 = \frac{- 18}{2}

Divide the numbers

More Steps

2 x - 1 = - 9

Move the constant to the right side

2 x = - 9 + 1

Add the numbers

2 x = - 8

Divide both sides

\frac{2 x}{2} = \frac{- 8}{2}

Divide the numbers

x = \frac{- 8}{2}
