Sagot :

Answer:

[tex]3 {x}^{2} - 5x + 4x = 3 {x}^{2} - 5 {x}^{2} + 9x \\ 3 {x}^{2} - x = - 2 {x}^{2} + 9x \\ 3 {x}^{2} + 2{x}^{2} = 9x + x \\5 {x}^{2} = 10x \\ 5x = 10 \\ x = \frac{10}{5} = 2 \\ x = 2 \\ thank \: you[/tex]

Answer:

[tex] \rm x = 2[/tex]

Step-by-step explanation:

[tex] \rm 3x ^ { 2 } -5x+4x=3x ^ { 2 } -5x ^ { 2 } +9x[/tex]

[tex] \rm 3x^{2}-x=3x^{2}-5x^{2}+9x [/tex]

[tex] \rm 3x^{2}-x=-2x^{2}+9x [/tex]

[tex] \rm 3x^{2}-x+2x^{2}=9x [/tex]

[tex] \rm 5x^{2}-x=9x [/tex]

[tex] \rm 5x^{2}-x-9x=0 [/tex]

[tex] \rm 5x^{2}-10x=0 [/tex]

[tex] \rm 5x -10 =0 [/tex]

[tex] \rm x = 10 \div 5 [/tex]

[tex] \bold{x = 2}[/tex]
