4x + 3 cannot equal 4x + 12:4x + 3 = 4x + 12 (given)3 = 12 (subtract 4x from both sides)

-9 < 4x + 3 < 11 Subtract 3 from each expression: -12 < 4x < 8 Divide each term by 4: -3 < x < 2

4[x+3]=4x+12 4x+12=4x+12 it's open.

Let the unknown number be X: -4x-10 = 2 -4x = 2+10 -4x = 12 x = -3 Remember that a minus multiplied by a minus is equal to a plus: -4*-3 = 12

subtracting gives 4x = -12 so x = -3

If the equasion is 12x+6-8x-4x-3+12 then the answer is 15.

3-3x

If 4x + 7 = 3... then x must equal -1

(4x2 - 13x - 12)/(4x+ 3) = (4x + 3)(x - 4)/(4x + 3) = (4x + 3)(x - 4)/(4x + 3) = x - 4 :)

If 4x + 3 = 9, then 4x must equal 6. Therefore x=1.5
