It has no solution. Equations have solutions, but expressions have not. Had you asked, 'What is the solution to -2x + 5 + 21 = 0 ?', then I would reply, '26 = 2x; therefore, x = 13', is your solution. You can check this, to see whether it is true. The equation is clearly true, if we substitute 13 for x: -2(13) + 5 + 21 = -26 + 5 + 21 = 0. The moral is that equations are statements and may be true or false. Mere expressions are not statements, and they are therefore neither true or false.

False !!! The origin is the point were the two axes intersect and is donoted by the point (0,0)
false. you can have a 3 by 5 or a 8 by 29
