On the equation (4-ax) / (x + 2) = 3 of X, if there is no solution, what is a equal to

Double x + 2
4-ax=3x+6
(a+3)x=-2
If a + 3 = 0, a = - 3
There is no solution
If a + 3 ≠ 0
Then x = - 2 / (a + 3)
If there is no solution, then this is root adding
So the denominator x + 2 = 0
-2/(a+3)+2=0
2/(a+3)=2
a+3=1
To sum up
a=-3,a=-2

If the fractional equation AX + 1 / x = 2 about X has no solution, then a is equal to?

Is ax + 1 a molecule? If ax + 1 / x = 2, then there will always be a solution
(ax+1)/x = 2
ax+1 = 2x
ax-2x = -1
(a-2)x = -1
When a = 2, the coefficient of X is 0, then the equation is meaningless

Given the equation system x + y = 7ax + 2Y = C, try to determine the value of a and C, so that the equation system: (1) has one solution; (2) has innumerable solutions; (3) has no solution

(1) When a = 3, C = 10, the equations have one solution; (2) when a = 2, C = 14, the equations have innumerable solutions; (3) when a = 2, C = 6, the equations have no solutions
