Answer:

x=10

Explanation:

15+3x=45

-15 -15 *first subtract 15 from both sides

3x=30 * then divide by 3 on both sides to get x by itself

/3 /3

x=10

Hey :)

x= 10

Subtract 15 from both sides
3x=45−15


Subtract 15 from 45 to get 30
3x=30

Divide both sides by 3.
x= 3/30


Divide 30 by 3 to get 10
x=10


Hope this helps :)
