Hi can i pls get some help oh this question pls
its 5x - 2 = -7

Answer 1

x = -1

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.

Answer 2

x= -1

Explanation:

5x1 would be -5 then -5 - 2 would be -7
