5x + 5 = x + 45<br><br> PLEASE HELP
Ostrovityanka [42]
5x+5=x+45

We'd rather not have x on both sides of the equation when trying to solve this. To eliminate the x on the right side, subtract both sides by x.

5x+5-x=x+45-x
4x+5=45

Let's get eliminate the "5" on the left side. Subtract both sides by 5.

4x+5-5=45-5
4x=40

To finish this, divide both sides by 4.

4x \div 4=40 \div 4
x=10

That is the answer. Hope this helps! :)
