Question

Solve the equation

d = 4

Evaluate

- 9 d = - 8 - 7 d

Move the variable to the left side

- 9 d + 7 d = - 8

Add the terms

More Steps

Evaluate

- 9 d + 7 d

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

(- 9 + 7) d

Add the numbers

- 2 d

- 2 d = - 8

Change the signs on both sides of the equation

2 d = 8

Divide both sides

\frac{2 d}{2} = \frac{8}{2}

Divide the numbers

d = \frac{8}{2}

Solution

More Steps

Evaluate

\frac{8}{2}

Reduce the numbers

\frac{4}{1}

Calculate
