2x+3<7 2x<7-3 2x<4 x<2
The inequality with the terms 2x, 3 and 7 can be written as 2x -3 = 7, 2x + 3 = 7, 2x * 3 = 7, and 2x/3 = 7. This means that the solutions are 5, 2, 7/4, and 21/2 respectively.
(2x + 3)(x + 1 ) = 2x^2 +5x +3

8x3 + 4x2 + 6x + 3 = 4x2(2x + 1) + 3(2x + 1) = (2x + 1)(4x2 + 3)
6x2 + 11x + 3 = 6x2 + 9x + 2x + 3 = 3x(2x + 3) + 1(2x + 3) = (2x + 3)(3x + 1)
2x+1 because -2 +3 = 1
2x + 3y = 1 y = 1/3 - 2x/3
The multiplicative inverse of 3+2x is 1/(3+2x).
(2x + 3)(x + 1)
x+3(x+1)=2x x + 3x + 3 = 2x 2x + 3 = 0 2x = -3 or x = -1.5
(2x + 1) (x + 3) = 2x2 + 7x + 3
