Answer:

x=2

Step-by-step explanation:

              -3x+7=1

subtract 7 from both sides: -3x+7-7=1-7

simplify: -3x=-6

divide both sides by -3:  [tex]\frac{-3x}{-3}=\frac{-6}{-3}[/tex]

simplify: x=2

Answer:

x=8/-3 or 2.6

Step-by-step explanation:

You have to isolate the "x" so move the +7 to the other side of the equation and you get this:

-3x=1+7

Now you can simplify and add 7 plus 1 which is 8

the equation should looks like this now:

-3x=8

Then to have x by itself you divide -3 on both sides.

-3 divided by -3x just leaves the x there and -3 divided by 8 is just 8/-3 or in decimal form it's 2.6

-3x/-3= x

8/-3= 8/-3 or 2.6

x= 8/-3

I'm not really good at explaining but I hope it helped :/
