3x\times 4-1=3x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 3x.
12x-1=3x
Multiply 3 and 4 to get 12.
12x-1-3x=0
Subtract 3x from both sides.
9x-1=0
Combine 12x and -3x to get 9x.
9x=1
Add 1 to both sides. Anything plus zero gives itself.
x=\frac{1}{9}
Divide both sides by 9.
