It has no solution because the discriminant of the quadratic expression is less than zero.
7x+20-15=7x+5
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.

Solution: 20+25=? 20x.2=4 20+4=24 ans.
The answer is 20+25=45
The sum of 20 added to itself 20 times is calculated by multiplying 20 by 20, resulting in 400. Therefore, the answer to the given equation is 400.
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.
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
2+2+2+10+5+5+5+20+20+20+20+20+20=151
65 + 65 + 65 + 90 + 90 + 90 + 90 + 50 + 50 + 50 + 50 + 50 + 50 + 20 + 20 + 20 + 20 + 20 + 20 + 20 = 995
