Solve f-120-8f - ScanMath

Evaluate

f - 120 - 8 f

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

f - 120 - 8 f = 0

Subtract the terms

More Steps

- 7 f - 120 = 0

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

- 7 f = 0 + 120

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

- 7 f = 120

Change the signs on both sides of the equation

7 f = - 120

Divide both sides

\frac{7 f}{7} = \frac{- 120}{7}

Divide the numbers

f = \frac{- 120}{7}

Solution

f = - \frac{120}{7}

Alternative Form

f = - 17. \dot{1} 4285 \dot{7}
