Add the numbers

70 f

70 f - 6

Solution

2 (35 f - 3)

Show Solution

f = \frac{3}{35}

Alternative Form

f = 0.0 \dot{8} 5714 \dot{2}

Evaluate

(7 f - 6) - (- 9 f \times 7)

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

(7 f - 6) - (- 9 f \times 7) = 0

Remove the parentheses

7 f - 6 - (- 9 f \times 7) = 0

Multiply the terms

7 f - 6 - (- 63 f) = 0

Subtract the terms

More Steps

Evaluate

7 f + 63 f

Collect like terms by calculating the sum or difference of their coefficients

(7 + 63) f

Add the numbers

70 f

70 f - 6

70 f - 6 = 0

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

70 f = 0 + 6

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

70 f = 6

Divide both sides

\frac{70 f}{70} = \frac{6}{70}

Divide the numbers

f = \frac{6}{70}

Solution

f = \frac{3}{35}

Alternative Form

f = 0.0 \dot{8} 5714 \dot{2}
