The first and second steps to solve the equation startfraction 3 x over 5 endfraction + 5 = 20 are shown below.

Third option.

Step-by-step explanation:

You need to remember the following properties:

1. The Multiplication property of equality states that:

If , then

2. The Subtraction property of equality states that:

If , then

Then, given the following equation provided in the exercise:

You can observe that, in the first step, 5 is subtracted from both sides of the equation.

Then, the property applied in the first step was the Subtraction property of equality:

In the second step, both sides of the equation are multiplied by , which is the reciprocal of .

Therefore, the property applied in the second step was the Multiplication property of equality):

600,000,000,000, or 6e14
