[tex]a)2x - 3 = 19 \\ = > 2x = 19 + 3 \\ = > x = \frac{22}{2 } \\ = > x = 11 \\ b)3x + 2 = 18 \\ = > 3x = 18 + 2 \\ = > 3x = 20 \\ = > x = \frac{20}{3} \\ = > x = 6.66666667 \\ c)4x - 4 = - 4 \\ = > 4x = - 4 + 4 \\ = > x = \frac{0}{4} \\ x = 0 \\ d)5x + 1 = 10 \\ = > 5x = 10 - 1 \\ = > 5x = 9 \\ = > x = \frac{9}{5} \\ x = 1.8[/tex]

therefore 1.8 =2 or x is not equal to 2
