Question

Solve the equation

k = 5

Evaluate

- 2 k = k - 7 - 8

Subtract the numbers

- 2 k = k - 15

Move the variable to the left side

- 2 k - k = - 15

Subtract the terms

More Steps

Evaluate

- 2 k - k

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

(- 2 - 1) k

Subtract the numbers

- 3 k

- 3 k = - 15

Change the signs on both sides of the equation

3 k = 15

Divide both sides

\frac{3 k}{3} = \frac{15}{3}

Divide the numbers

k = \frac{15}{3}

Solution

More Steps

Evaluate

\frac{15}{3}

Reduce the numbers

\frac{5}{1}

Calculate

5

k = 5
