3x-1=0 set the equality to 0
3x=1 isolate the x term
3x/3=1/3 divite both sides of the equation by the number that stays next to x
x=1/3 get the answer ;))

3x1=7 1+7=8 8x3=24
If 5x plus 3y equals 13, the x equals 2 and y equals 1. This is because 5x2=10 and 3x1=3, and 10+3=13.
Nothing will solve an expression. You need an equation (an equality or an inequality) beofre a solution of any kind is possible. Tha means you need something on both sides of the equality (or inequality) sign.
No because it is an algebraic equation that includes an equality sign thus: 5x=35 and the solution is x=7
