First you add 3x+x because they are like terms.

3x+x-7=10

Your New Simplified Equation:

4x-7=10

Now, you have to take out the -7 by adding a positive 7. Also you have to add +7 on the other side so add 7 to 10.

Your New Simplified Equation:

4x=17 Now, you divide both sides by 4.

Your New Simplified Equation:

x= 17/4 So, that's your answer :)
