Answer 1

Answer:

Step-by-step explanation:

The steps to solving an equation are those that undo the operations done to the variable. Here, the variable is multiplied by 2/3 and 15 is added to the product.

We undo the addition of 15 by subtracting 15 (from both sides of the equation).

We undo the multiplication by 2/3 by multiplying both sides of the equation by its inverse, 3/2.

It is useful to do simplification after each of these steps.

Attention needs to be paid to the signs. When 15 is subtracted from 9, a negative result is obtained. When that is multiplied by a positive number (3/2), a negative result remains.
