x=5.54x+1= 2x+12-1 -14x=2x+11-2x -2x2x=11/2 /2x=5.5
2x + 7 = 1 Therefore, 2x = -6 x = -6/2 x = -3
-2x - 2y = -122x + 2y = 122y = 12 - 2xy = 6 - x
3x-2 = 2x+3 3x-2x = 3+2 x = 5
2x + 4 = 16 2x = 16 - 4 2x = 12 x = 12/2 x = 6
X=6
x = 4 and y = 0
2x + 12 y =36subtract 2x from both sides12y = 36 - 2xdivide both sides by 12y = (36 - 2x)/12
2x+a=p 2x=p-a x=.5p-.5a
12 = 2x + 6 subtract 6 from both sides 6 = 2x divide both sides by 2 3 = x
y= -2x
2x +n5y=12
-2x = -4x + 24 -2x + 4x = 24 2x = 24 x = 24/2 x = 12
