A\times 3+4=2
Swap sides so that all variable terms are on the left hand side.
A\times 3=2-4
Subtract 4 from both sides.
A\times 3=-2
Subtract 4 from 2 to get -2.
A=\frac{-2}{3}
Divide both sides by 3.
A=-\frac{2}{3}
Fraction \frac{-2}{3} can be rewritten as -\frac{2}{3} by extracting the negative sign.
