Solving

25 = x - .2(x-14)

distribute

25 = x - .2x + 2.8

simplify

25 = .8x + 2.8

-2.8 from both sides to get rid of the 2.8 on the right side

22.2 = .8x

divide by .8 to find x

27.75 = x

----------Checking-----------

25 = 27.75 - .2(27.75 - 14)

25 = 27.75 -.2(13.75)

25 = 27.75 - 2.75

25 = 25

First distribute the .2 to (x-14) to get: $25 = x-.2x-2.8

Then simplify the right side of the equation: $25 = .8x-2.8

Then add 2.8 to each side. (I'm not sure if the 2.8 is in dollars or not, but I'm going to assume that that's what you meant.) : $27.80 = .8x

Then divide by .8 to get the x-value: x = $34.75

If the 2.8 was not a dollar amount, you can simply add it to the left as well: $25+2.8 = .8x

And then divide: x = $20+2.24

first distribute the -.2 into the parenthesis. now you have

$25=x-.2x+2.8. now to get rid of the decimals I would multiply the whole equation by 10, that way you'll have whole numbers to work with instead. so after mult by 10 you have

$250=10x-2x+28.

now get the x terms toget ther. since on the same side just do what it says, 10x-2x=8x.

now you have $250=8x+28. now to solve for x, get rid of the 28 by doing the opposite of it, so subtract 28 from both sides. now you have

$242=8x. now the last step is to divide both sides by 8 to get by itself. so you get

x=$30.25

25 = x- .2x + 2.8

22.2 = x - .2x subtract 2.8 from both sides

22.2 = .8x combine the like terms

27.75 =x divide both sides by .8
