It is known that the equation of X: ax + 4 = 1-2x is a linear equation of one variable, then the condition that coefficient a should satisfy is______ ．
From the original equation, we get that (a + 2) x + 3 = 0, ∵ the equation about X: ax + 4 = 1-2x is exactly one variable linear equation, ∵ a + 2 ≠ 0. The solution is a ≠ - 2. So the answer is a ≠ - 2
On the condition that the equation AX + B = 0 has innumerable solutions______ ．
On the one variable linear equation AX + B = 0 of X, the condition is: a = b = 0. So the answer is: a = b = 0
