Sagot :

Answer:

x = -3

Step-by-step explanation:

1. add 9 to both sides -9x-9+9=x+21+9

2. simplify -9x=x+30

3. subtract x from both sides -9x-x=x+30-x

4. simplify -10x=30

5. divide both sides by -10 -10x/-10 = 30/-10

simplify and you're done!

Answer:

x=-3

Step-by-step explanation:

Original equation: -9x-9 = x+21

Add 9 to both sides: -9x=x+30

Subtract x from both sides: -10x=30

Divide by -10  on both sides: x=-3.
