10x-3x=9-1 First, put the variables on one side,and the normal numbers on the other. Keep in mind that u have to change the sign (+ or -) when you switch sides.
Well, first you'd have to get the x by it's self. 10x+1=3x+9 Subtract 3x from each side and you'll have the x on only one side rather than two. 7x+1=9 Now I'd get rid of the 1 on the x's side. So just subtract 1 from each side. 7x=8 Then you should make it so the seven isn't there with the x either. Just divide each side by 7. Answer: x=8/7 Each time you change something on one side, you must do the same to the other side. T find the value of a variable in an equation, simple seclude it so it's on it's own without number to make things confusing. The answer was x=8/7 btw.
