-9 < 4x + 3 < 11 Subtract 3 from each expression: -12 < 4x < 8 Divide each term by 4: -3 < x < 2
8x + 15
x=2.75 This follows from the equation (4x - 3) + 11 = 19 and 4x = 11
2x + 3 + 3x = x + 11 5x + 3 = x + 11 4x + 3 = 11 4x = 8 x = (8/4) x = 2

3-3x
If 4x + 7 = 3... then x must equal -1
If 4x + 3 = 9, then 4x must equal 6. Therefore x=1.5
2x + 3 + 3x = x + 11 5x + 3 = x + 11 4x + 3 = 11 4x = 8 x = (8/4) x = 2
= 3

4x + 3 = 47 4x = 47-3 4x = 44 x = 44/4 x = 11
Assuming that your equation is:_2X - 8 = -4X +3, adding 8 to both sides gives,2X = -4X + 3 +8, gives2X = -4X +11, then adding 4X to both sides,6X = 11 which gives X = 11/6 = 1.83333.your original equation was NOT an equation - that is an expression where two things were equal to each other.
It is: 11-6x as a simplified expression
