    Answer:

    x = -1

    Step-by-step explanation:

    The key thing to remember is that every operation you do on either side needs to be done on the other.

    Let’s start by getting rid of that -2  you can do that by adding 2 to both sides of the equals sign:

    5x – 2 = -7

    5x – 2 + 2 = -7 + 2

    5x – 0 = -5

    5x = -5

    The next step is to get rid of that 5 on the left.  We can do that by dividing both sides by 5:

    5x = -5

    5x ÷ 5 = -5 ÷ 5

    x = -1

    And there you have it! x is equal to negative one.
