The answer to 1 over 2x plus 13 equals 9 is x equals -8.
2x + 9 = 6x + 1 9 - 1 = 6x - 2x 8 = 4x x = 2
2x+1 = 9 2x = 9-1 2x = 8 x = 4
2x + 1 = 9 2x = 9 - 1 2x = 8 2x/2 = 8/2 x=4
6 + 2x = 5x + 9 , 6 - 9 = 5x - 2x , -3 = 3x , x = -1
2x = -x +9
2x + 3y = 9x = 3, y = 1 therefore 6 + 3 = 9
(-1,-2)
(2, 1)
x=-1/2
-2x+9=x+1-x........-x-3x+9=1.....-9...-9-3x=-8-3x/-3 | -8/-3\ /........\ /x=8/3
5x+18 = 2x+9 5x-2x = 9-18 3x = -9 x = -3 and y = 3
