Solve -72b-45 -2b+6

Evaluate

- 72 b - 45 - 2 b + 6

To find the roots of the expression,set the expression equal to 0

- 72 b - 45 - 2 b + 6 = 0

Subtract the terms

More Steps

- 74 b - 45 + 6 = 0

Add the numbers

- 74 b - 39 = 0

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

- 74 b = 0 + 39

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

- 74 b = 39

Change the signs on both sides of the equation

74 b = - 39

Divide both sides

\frac{74 b}{74} = \frac{- 39}{74}

Divide the numbers

b = \frac{- 39}{74}

Solution

b = - \frac{39}{74}

Alternative Form

b = - 0.5 \dot{2} 7 \dot{0}
