Q:
# I need this answer ASAPWhich equation has no solution?A. 9x + 9 = 11x β 2x + 9B. 7x + 30 = x + 6(x + 5)C. -5x + 9 = 2x + 9 - 7xD. 7x - 6 = x + 6(x + 5)β

Accepted Solution

A:

Answer:D. 7x - 6 = x + 6(x + 5)βStep-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)β7x-6 = x+6x+307x-x-6x-6-30= 0-36β 0so -36 β 0 ... so no solution A. 9x + 9 = 11x β 2x + 9 Β 9x-11x+2x+9-9=0 Β 0=0 Β Β have solution, Real, trueB. 7x + 30 = x + 6(x + 5)7x+30 = x+6x+307x-x-6x+30-30= 0 0=0have solution, Real, trueC. -5x + 9 = 2x + 9 - 7x-5x-2x+7x+9-9= 0-7x+7x=00=0have solution, Real, true
