Question

How do you solve `0.06x + 0.03(4000 - x) = 153`?

Answer 1

`x=110`

Explanation:

`0.06x+0.03(4000-x)=153`

Start by distributing 0.03.

`0.06x+120-0.03x=153`

Next, move the equation around to get numbers on one side and letters on the other. Don't forget to change their signs when moving them onto their opposite sides (ie: negative to positive or positive to negative). In this case, I had to move 120 over to the right side of the equation and change its sign to negative.

`0.06x-0.03x=153-120`

Simplify your equation on both sides.

`"0.03x"/0.03=33/0.03`

Divide by 0.03 to get x by itself.

`x=110`

You now have your final answer! :)
