9x + 2x + 26 is an expression, not an equation (or inequality). It therefore cannot have a solution so that its solution set is the null set. There is nothing in the solution set - no integers, rationals, irrationals: nothing!
Not being an equation, it does not have a "solution" per se. If you wish to factor it, you can do it like so: x2 + 20 - 9x = x2 - 5x - 4x + 20 = x(x - 5) - 4(x - 5) = (x - 4)(x - 5) If that expression is equal to zero, then x would be equal to 4 or 5.
Without an equality sign the given terms can't be considered to be an equation but the terms can be simplified to: 9x-1016
If you mean: 7x-53 = 9x Then the solution is: x = -26.5

9x - 9 = 36 9x = 45 x = 5
This is a linear equation. The value x = -1 is the solution to this equation.
An equation never equals a number, but its solution often does.-- An equation with a solution of six: [ 3x - 14 = 4 ]-- An equation with a solution of three: [ 14 - 10x = -16 ]-- An equation with both solutions: [ x2 - 9x + 20 = 2 ]An equation that equals 6 is 10 - 4 = 6An equation that equals 3 is 10 - 7 = 3
Presumably this is a quadratic equation question asking you to find the solution of 2x2+9x-5 = 0 First factorise the expression in the equation in order to find its solution. (2x-1)(x+5) = 0 Solution: x = 1/2 or x = -5

It is an equation in a single variable, x.And, although the question does not ask, the solution is x = 5.It is an equation in a single variable, x.And, although the question does not ask, the solution is x = 5.It is an equation in a single variable, x.And, although the question does not ask, the solution is x = 5.It is an equation in a single variable, x.And, although the question does not ask, the solution is x = 5.

The answer to this equation is the number 99. This is taught in high school math.
If you mean: 7x-53 = 9x Then the solution is: x = -26.5
-20 + 9x = -17-20 + 17 = -9x-3 = -9x |: (-9)0.333... = xx = 0.333...
