(x + 4) + (x + 5) = 2x + 9
x + 5 + 4 = x + 9
If you mean: x+4(x+5) then it is 5x+20
3 plus 4 x plus 5 31 when simplified would give x = 23/4.
x+4x+5=5x+5
(x + 4) + (x + 5) = 2x + 9
x + 5 + 4 = x + 9
If you mean: x+4(x+5) then it is 5x+20
(x + 4) + (x + 5) = 2x + 9
3 plus 4 x plus 5 31 when simplified would give x = 23/4.
If its x+4x+5 then: 5x+5
x+4x+5=5x+5
(x+4)(x+5) = 0 x = -4 v x= -5 However this can also be an answer: (x+4)(x+5) = 0 x2 + 9x + 20 = 0
If: x+(-5) = 4 Then: x = 9
[(7+3)/(x+4)] / [(x-5)/(2-4)] =[(7+3)/(x+4)] * [(2-4)/(x-5)] =[10*(x-5)] / [-2*(x+4)] =-5*[(x-5)/(x+4)]
If: x + 2/2 + x + 5/7 = 4 Then: x = 8/7
(x + 4) / (x3 - 11x + 20) = (x + 4) / (x2 + 4x - 5)(x + 4) = 1 / (x2 + 4x - 5) = 1 / (x + 5)(x - 1), where x ≠ -4
