Question

(a-12)x=a+8 if this equation has no solution and a is a constant. what is the value of a

Answer 1

Answer:

a=12

Step-by-step explanation:

If you solve for x, you divide by (a-12) to isolate x on the left side:

x = (a+8)/(a-12)

If the numerator is 0 you will be dividing by zero, which invalidates the solution. This will happen for a=12.
