Answer:

#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! :)
