The answer to 1 over 2x plus 13 equals 9 is x equals -8.
2x + 5 = 13 2x = 8 2x/2 = 8/2 x=4
2x-3y=13
3x+5 = 2x+13 3x-2x = 13-5 x = 8
2x + 1 = 13; 2x = 12; x = 6
7X + 4 - 2X + 9 = 0 Move all constants to the opposite side- 7X - 2X = -9 - 4 Simple addition and subtraction- 5X = -13 Get X by itself by division- X = -13/5 There you go :)
2x plus 3y
-2x+13y=11 13y=2x+11 y=2x/13 + 11/13
2x+3y=13 3x-y=3 x=2
x-29 = 13+2x x-2x = 13+29 -x = 42 x = -42
84
X= -8
