Suppose a body is being acted upon up two opposite forces as shown. Then we write its equation of motion/force as F+F21 = m1a but shouldn't the equation be F+m1a=F21

See, net force is what gives the accelaration. So the net force here is(in vector form) F + F21. if it was not in vector then we would have taken it as F – F12.
So this net force(again in vector form) F + F12 = m1 * a. That’s all no?
