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 :/
