Hello - let's do this step by step. Show your work.
You're asking: 9(8−x)=3x.
Now, simplify both sides of the equation.
9(8−x)=3x
(9)(8)+(9)(−x)=3x (To do that, distribute)
72+−9x=3x
−9x+72=3x
Now, subtract 3x from both sides.
−9x+72−3x=3x−3x
Simplify,
−12x+72=0
After, subtract 72 from both sides.
−12x+72−72=0−72
−12x=−72
Last thing, divide both sides by -12.
-12x/12 = -72/-12
Divide.
Therefore, you have x = 6 as your final answer.
Hello there!
9(8-x)=3x
Use the Distributive Property to distribute 9:
72-9x=3x
Move all the variables to the left side. Be sure to use the opposite operation!
-9x-3x=-72
-12x=-72
Divide both sides by 12 in order to isolate x:
x=6
Hope this helps you!
