28 + 2x = 120 2x = 120 - 28 2x = 92 x = 92/2 x = 46
(12)2x = 28(2x) log(12) = log(28)2x = log(28) / log(12) = 1.34098 (rounded)x = 0.67049 (rounded)
3x + 8 = 2x +28 3x - 2x = 28 - 8 x=20
(12, 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
(12)2x = 28(2x) log(12) = log(28)2x = log(28) / log(12) = 1.34098 (rounded)x = 0.67049 (rounded)
3x + 8 = 2x +28 3x - 2x = 28 - 8 x=20
14y - 2x = 28 14y = 2x + 28 y = x/7 + 2 Therefore, the slope is 1/7.

8x+4 = 2x+28 8x-2x = 28-4 6x = 24 x = 4
2x + 15 = 8x + 43 -6x = 28 x = -6 / 28 = -3 / 14
the equation can also be written 2x+28=152, subtract 28 from each side :2x=124, divide each side by 2 and you get x=62
x = 12, y = 1
6x = 8x+28 6x-8x = 28 -2x = 28 x = -14
x - 3x + 7 = 28 Collect the x together: x - 3x = (1-3)x = -2x → -2x + 7 = 28 Collect the numbers together - subtract 7 from both sides →-2x = -21 Divide both sides by -2 to get what one x is: x = -10.5
If 5 x equals 9 plus 2x then x equals?
