This is not an equation. Where is the "equal" sign? However, this could be simplified to: 17+6x

Normally, there wouldn't be a (-) after the eight. Without the (-) sign it would be 72+8x+7x. I am pretty good with algebra and can't ever recall seeing an equation with a minus sign between a number and the parenthesis. Are you sure the equation is written correctly?

a) That's not an equation, that's an expresion. Equations state that one expresion is equal to some other expresion. What you have stated is in fact meaningless.
b) Expand the brackets, then add the similar terms.
c) Don't post your homework on Yahoo Answers, the point is that you do it yourself and learn something. Then after you have graduated and you have to do it for real, you don't screw it up and cause the deaths of thousands of people.

WELL IS THAT EQUATION = 0 OR NOT
IF NOT
THEN
8-(-9+X)+7X
8+9-X+7X
17+6X
IF ITS = 0
THEN
8-(-9+X)+7X = 0
8+9-X+7X = 0
17+6X = 0
6X = -17
AND THE VALUE OF X
X = -17/6 OR -2.833 ANS
GOT IT
