Question

Is the answer to this x=-21
3-6/7x=21

Answer 1

(3-6)/(7x) = 21
if you place -21 you will get a really large negative number in the denominator compared to the numerator which will result in a extremely small number

Answer 2

It is 3- 6 over 7x

Answer 3

3-(6/7x) will also do the same but you are subtracting 3 by a small number

Answer 4

o

Answer 5

if you multiply both sides by x you can see that you will get (3-6)/7 = 21x

Answer 6

you can simplify 3-6 to -3 so you will result in -3/7 = 21x

Answer 7

then you can divide both sides by 21 to get -3/(7*21) = x
and that is your answer

Answer 8

to check you can place your answer of x into the original equation and it should equal 21, the right hand side of the equation

Answer 9

thanks
