2x + 7 = 1 Therefore, 2x = -6 x = -6/2 x = -3
3x-2 = 2x+3 3x-2x = 3+2 x = 5
x=1

13
-2x+13y=11 13y=2x+11 y=2x/13 + 11/13
x-29 = 13+2x x-2x = 13+29 -x = 42 x = -42
-9-2x+x = -13 -2x+x = -13+9 -x = -4 x = 4
(x - 3)(x + 5)
2x+a=p 2x=p-a x=.5p-.5a
y= -2x
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
