Answer:
D. 7x - 6 = x + 6(x + 5)
Step-by-step explanation:
a equation will have no solution if the final value is not real or not equal
D) 7x - 6 = x + 6(x + 5)
7x-6 = x+6x+30
7x-x-6x-6-30= 0
-36≠0
so -36 ≠ 0 ... so no solution
A. 9x + 9 = 11x – 2x + 9
9x-11x+2x+9-9=0
0=0
have solution, Real, true
B. 7x + 30 = x + 6(x + 5)
7x+30 = x+6x+30
7x-x-6x+30-30= 0
0=0
have solution, Real, true
C. -5x + 9 = 2x + 9 - 7x
-5x-2x+7x+9-9= 0
-7x+7x=0
0=0
have solution, Real, true
