Answer:

x = 9

Step-by-step explanation:

10x - 30 = 15 + 5x

First, subtract 5x from both sides to get all x terms on the left side.

5x - 30 = 15

Now add 30 to both sides.

5x = 45

Divide both sides by 5.

x = 9

Answer:

x =9

Step-by-step explanation:

10x-30=15+5x


Subtract 5x from each side

10x-5x -30 = 15+5x-5x

5x-30 = 15

Add 30 to each side

5x-30+30 = 15+30

5x =45

5x/5 = 45/5

x =9
