Answer:

[tex]x=-2[/tex]

Step-by-step explanation:

[tex]x-x(3x-5)=x-2(x^2+x)-x^2-14[/tex]

[tex]x-3x^2+5x=x-2x^2-2x-x^2-14[/tex]

[tex]-x[/tex]                 [tex]-x[/tex]  

[tex]-3x^2+5x=-2x^2-2x-x^2-14[/tex]

[tex]-3x^2+5x=-3x^2-2x-14[/tex]

[tex]+3x^2[/tex]             [tex]+3x^2[/tex]

[tex]5x=-2x-14[/tex]

[tex]+2x[/tex]   [tex]+2x[/tex]

[tex]7x=-14[/tex]

[tex]\frac{7x}{7} =\frac{14}{7}[/tex]

[tex]x=-2[/tex]

Hope this helps!
