If 4/3x - 1/2 = 0 then x=

4/3x - 1/2 = 0 Given

4/3x = 1/2 Add 1/2 to both sides

x = 3/8 Multiply each side by 3/4

It is important when doing equations like these to remember that you need to multiply by the reciprocal of the fraction, not divide by it. For example, if another you have 1/2x = 1, you need to multiply by 2/1 or 2, not divide by 1/2.
