The problem is:
3x + 2x -10= 180
The answer is:
x = 38
Here are the steps:
3x + 2x -10= 180
5x -10= 180
5x = 180+10
5x = 190
x = 38

All you do is add the ten to the 180 to get 190. Then you add the 3x and the 2x since they are like terms giving you 5x. Then you just divide 190 by 5 and you get the value of x.

have to add the variables.... which is 5x then to get the negative 10 to the 180 you have to add on both sides like -10+10 equals 0 and 10+180= 190 so now you have 5x=190 the you divide 6 by both sides... 5/5 is 1 so it leaves the x the 190/5 is 38 so the answer is x=38

3x+2x-10=180
you simplify it by adding 3x+2x
5x-10=180
then you want to get the 10 on the other side so you add ten to 180
5x=190
190 divided by 5
which is 38
so x=38

I love these problems!!! It's like a super easy class of algebra!!!
3x+2x-10=180
5x-10=180
-10 = -10
5x=170
/5= /5
x=134
Ur welcome. Next time u should do ur own work. I just like doing that stuff

the answer would be 38
first, you combine 2x and 3x into 5x
then add 10 to both sides
then you divide each side by 5 and x=38

5x-10= 180
5x= 180 + 10
5x= 190
x=190 / 5
x = 38

5x-10=180
-10 -10
subtract 10 from both sides because what you do to one side you have to do to the other
5x= 170
divide by 5 on both sides and you get your answer
