Question

-7=6x+1 what is the solution?

Answer 1

First, subtract 1 on both sides of the equation, since you are originally adding it

-7 = 6x + 1
-7 - 1 = 6x + 1 - 1
-7 - 1= 6x

So what is -7 - 1?

Answer 2

-8?

Answer 3

Correct, so we have

-8 = 6x

Now we divide 6 on both sides of the equation

-8/6 = 6x/6

-8/6 = x

So that tells us that \(\dfrac{-8}{6}\) = x

But we can simplify that fraction. Do you know how to simplify fractions?

Answer 4

Not really.

Answer 5

wouldnt it be -4/3?

Answer 6

Yes =)

Answer 7

-8/6 is simplified to -4/3

Answer 8

But thats an improper fraction how do i change that to a mixed number?

Answer 9

It is proper =) For it to be improper the denominator has to be greater than the numerator. In this case, it isn't
