Seven times a number is 9 less than the product of the number and -20. what is the number? show steps

the number is -1/3

Step-by-step explanation:

First thing, I am going to write out the equation for this:

-20x - 9 = 7x

Then, I will add 20x to both sides, so:

-9 = 27x

Then I will divide both sides by 27 to get the x alone

so:

x = -1/3

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

hello! just here for points! though i wish i knew!
