Solve 25(1-4x)2-28=-12

Evaluate

25 (1 - 4 x) \times 2 - 28 = - 12

Multiply the terms

50 (1 - 4 x) - 28 = - 12

Move the expression to the left side

50 (1 - 4 x) - 28 - (- 12) = 0

Subtract the numbers

50 (1 - 4 x) - 16 = 0

Calculate

More Steps

34 - 200 x = 0

Move the constant to the right-hand side and change its sign

- 200 x = 0 - 34

Removing 0 doesn't change the value,so remove it from the expression

- 200 x = - 34

Change the signs on both sides of the equation

200 x = 34

Divide both sides

\frac{200 x}{200} = \frac{34}{200}

Divide the numbers

x = \frac{34}{200}

Solution

x = \frac{17}{100}

Alternative Form

x = 0.17
