Solve (-9k 1)-(4k-3)

Question

Simplify the expression

- 13 k + 3

Evaluate

(- 9 k \times 1) - (4 k - 3)

Multiply the terms

(- 9 k) - (4 k - 3)

Remove the parentheses

- 9 k - (4 k - 3)

If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses

- 9 k - 4 k + 3

Solution

More Steps

Evaluate

- 9 k - 4 k

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

(- 9 - 4) k

Subtract the numbers

- 13 k

- 13 k + 3

Show Solution

Find the roots

k = \frac{3}{13}

Alternative Form

k = 0. \dot{2} 3076 \dot{9}

Evaluate

(- 9 k \times 1) - (4 k - 3)

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

(- 9 k \times 1) - (4 k - 3) = 0

Multiply the terms

(- 9 k) - (4 k - 3) = 0

Remove the parentheses

- 9 k - (4 k - 3) = 0

Subtract the terms

Subtract the terms

More Steps

Evaluate

- 9 k - 4 k

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

(- 9 - 4) k

Subtract the numbers

- 13 k

- 13 k + 3

- 13 k + 3 = 0

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

- 13 k = 0 - 3

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

- 13 k = - 3

Change the signs on both sides of the equation

13 k = 3

Divide both sides

\frac{13 k}{13} = \frac{3}{13}

Solution

k = \frac{3}{13}

Alternative Form

k = 0. \dot{2} 3076 \dot{9}
