In the equation: F is force, m is mass, and a is acceleration. Divide both sides by a, and you have:m = F/a, which is Force divided by acceleration.
(4/9) x = That's not an equation. If there were a number after the 'equals' sign, then we could calculate the value of 'x'. But as it is, there's no question there, so there's nothing to solve.
a equals 5
X= (3/5 , -2)
