There is no equation in the question, only an expression. An expression cannot have a solution.

That will depend on the plus or minus value of 20 or perhaps there is an equality sign missing and so therefore it has no solution.

20 + 20 + 20 + 20 + 20 + 20 + 20 + 20 + 20 + 20 + 20 + 20 + 20 + 20 + 20 + 20 + 20 + 20 + 20 + 20 = 400.

Solution: 20+25=? 20x.2=4 20+4=24 ans.

The answer is 20+25=45

3x^2=-20 so x^2=-20/3 this has no real roots but the plus of minus i(square root of 20/3) is a solution if we allow complex numbers.

2+2+2+10+5+5+5+20+20+20+20+20+20=151

20 + + 20 + 20 = 60

65 + 65 + 65 + 90 + 90 + 90 + 90 + 50 + 50 + 50 + 50 + 50 + 50 + 20 + 20 + 20 + 20 + 20 + 20 + 20 = 995

20 plus 20 equals 4020 plus 20 = 40

18 - 3n + 2 = n + 20 - 4n gather terms together on both sides of equation - 3n + 20 = - 3n + 20 0 = 0 =============no true solution here Actually, it's an infinite number, not "no solution" because it can also be done to end with n=n. I realize you didn't strictly say "no solution" but that's what it sounds like, so I'm just clarifying. -3n+20=-3n+20 -3n=-3n n=n

this is clearly a trick question. 20 plus 20 plus 20 is equal to 60 and there is 60 minites in 1 whole hour so 20 plus 20 plus 20 is equal to 1.

20 x 7 = 20 + 20 + 20 + 20 + 20 + 20 + 20 = 140 The answer is 140.

20 + 50 + 20 + 10 = 50 = 150

20 + 12 + 32 + 20 + 30 + 72 = 186

The solution is:- x = 0 and y = 5

No. The mole of solution is equal to mole of solute plus mole of solvent (solVENT !, not solution)

16 + 16 + 16 + 17 + 18 + 18 + 18 + 19 + 19 + 20 + 20 + 20 + 21 = 238

In a neutral solution, the H plus is equal to OH-. The pH level in such a solution is usually at 7.
