x = - 9

Step-by-step explanation:

Step 1: Write out expression

5 (x + 13) = 20

Step 2: Distribute

5x + 65 = 20

Step 3: Isolate x

5x = - 45

x = - 9

And we have our answer!

Brayan Lutz · Answer 2

-9

Step-by-step explanation:

Let the number be x.

5 (x+13) = 20

Expand.

5x+65 = 20

Subtract 26 on both sides.

5x = 20 - 65

5x = - 45

Divide 5 into both sides.

x = - 45/5

x = - 9

The number is - 9.
