"sum" is not the right word here. All the bits are not being added: there is an equals sign. But 9x plus 14x can only be 23x, so that 23x + 8 = 0. Take 8 from each side of the equality so 23x = -8, and then divide both sides by 23 to get x = -8/23
Don't confuse"x" with the multiplication sign. For that reason, in algebra, a curly x is used wherever possible.
If you mean: -5x+14x = 48+14 then 9x = 62 and the value of x equals 62/9 = 6.'8' recurring '8'
23x - 9x = 14x
x2 + 14x + 45 = 0 => x2 + 9x + 5x + 45 = 0 => x(x + 9) + 5(x + 9) = 0 (x + 9)(x + 5) = 0 so that x = -5 or x = -9
it equals 13X.
The slope is 0.
14x is the sum of 5x and 9x
so 14x = -42, making x = -3
If you mean: -5x+14x = 48+14 then 9x = 62 and the value of x equals 62/9 = 6.'8' recurring '8'
It is 14x+4 simplified
23x - 9x = 14x
x2 + 14x + 45 = 0 => x2 + 9x + 5x + 45 = 0 => x(x + 9) + 5(x + 9) = 0 (x + 9)(x + 5) = 0 so that x = -5 or x = -9
it equals 13X.
The slope is 0.
If x equals 10 and y equals 10, then 9x plus 8y equals 170.

9x + 9 = 135 9x = 126 x = 14
It is 9x
