2x+3/5 =2-x/3 +x
[tex]2x + \frac{3}{5} = 2 - \frac{x}{3} + x \\ 30x + 9 = 30 - 5x + 15x \\ 20x = 21 \\ x = \frac{21}{20} = 1 \frac{1}{20} [/tex]
2x2 - (2x+1)(x-2)=5
[tex]2 {x}^{2} - (2x + 1)(x - 2) = 5 \\ 2 {x}^{2} - (2 {x}^{2} - 2x + x - 2) = 5 \\ 2 {x}^{2} - 2 {x}^{2} + 2x - x + 2 = 5 \\ x = 3[/tex]
Mam nadzieję że pomogłam
