Seven less than twice a number is the same as nine times the number. Find the number.

x = -1

Step-by-step explanation:

2x - 7 = 9x

Subtract 2x from both sides: -7 = 7x

Divide both sides by 7: -1 = x

Now plug in 7 for every value of x in the original equation to make sure you are correct:

2(-1) - 7 = 9(-1)

-2 - 7 = -9

-9 = -9

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
