REMEMBER; you can do anything with an equation as long as you do it on both sides! 4x + 9x - 4 = 2x + 8 Lets first move the "x" to one side.  ... 4x + 9x - 4 - 2x = 8           I subtracted - 2x from both sides. 4x + 9x - 2x = 8 + 4 I added 4 to both sides -//- = 12 I sumed up what I could on the right side 13x - 2x = 12 I simplyfied the left side 11x = 12 I subtracted on the left side x = 12/11 I divided 11 from both sides anwser: x = 1.09090909091

First step is to simplify: 4x+9x+−4=2x+8 Combine Like Terms: (4x+9x)+(−4)=2x+8  13x+−4=2x+813x−4=2x+8 Now you need to subtract 2x from both sides: 13x−4−2x=2x+8−2x 11x−4=8 Now, add 4 to both sides: 11x−4+4=8+4  11x=12 Then. divide both sides by 11: 11x/11=12/11 And now your answer is: x=12/11 Good luck with your studies, I hope this helps!
