zmey [24]

Answer:

x = t/4 and y = (t+17)/3

(a-12)x = a+8 in the equation to the left, a is a constant. if the equation has no solutions, what is the value of a?

ohaa [14]

Answer:

<h2>The value of a is 12.</h2>

Step-by-step explanation:

The equation is given by (a - 12)x = a + 8.

In order to get the solution of the equation, that is the value of x, the above equation is needs to be divided by a - 12. (a - 12) will be in the denominator.

The solution can not be found, if the value of a - 12 will be 0, that is a = 12.
