3x + 8 = 2x +28 3x - 2x = 28 - 8 x=20
8x+4 = 2x+28 8x-2x = 28-4 6x = 24 x = 4
28 + 2x = 120 2x = 120 - 28 2x = 92 x = 92/2 x = 46
2x+10=12 2x=2 x=1
2x + 10 = 182x = 8x = 4
3x + 8 = 2x +28 3x - 2x = 28 - 8 x=20
x = 9 and y = 28
x = 12, y = 1
8x+4 = 2x+28 8x-2x = 28-4 6x = 24 x = 4
28 + 2x = 120 2x = 120 - 28 2x = 92 x = 92/2 x = 46
2x+10=12 2x=2 x=1
2x + 10 = 182x = 8x = 4
x = 12 and y = 1 (12, 1)
x equals 19
If your question was 2X + 5 =10. X equals what? Then X=2.5
2x + 15 = 8x + 43 -6x = 28 x = -6 / 28 = -3 / 14
