Answer:
x=3
Step-by-step explanation:
The first thing we have to do is distribute
When distributing, we multiply 5 times the x and 5 times the 3, so basically everything in the parentheses gets multiplied by 5
Our equation now becomes, 5x+15=30
We have to isolate the 5x, so we subtract 15 from each side. This cancelles out the 15 and cuts the 30 down to 15 since 30-15=15
Now our equation is 5x=15
To get the x all by itself, we need to get rid of the 5 before it. We do this by dividing 5 to cancel it out. Since we do something to one side of the equation, we must do it to the other side of the equation, so now we divide 15 by 5 as well
Our final equation is…
x=3
