Solve 9=(-7/10)a-12

Evaluate

9 = (- \frac{7}{10}) a - 12

Remove the parentheses

9 = - \frac{7}{10} a - 12

Swap the sides of the equation

- \frac{7}{10} a - 12 = 9

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

- \frac{7}{10} a = 9 + 12

Add the numbers

- \frac{7}{10} a = 21

Change the signs on both sides of the equation

\frac{7}{10} a = - 21

Multiply by the reciprocal

\frac{7}{10} a \times \frac{10}{7} = - 21 \times \frac{10}{7}

Multiply

a = - 21 \times \frac{10}{7}
