Answer:

3[tex]x^{2}[/tex] -2x +5=0

Step-by-step explanation:

Combine liked terms:

3[tex]x^{2}[/tex]+5x+x-1x+6+2=7x+3

3[tex]x^{2}[/tex]+6x-1x+8=7x+3

3[tex]x^{2}[/tex]+5x+8=7x+3

Subtract 3: 3[tex]x^{2}[/tex]+5x+8-3=7x+3-3

3[tex]x^{2}[/tex]+5x+5=7x

Now subtract 7x:

3[tex]x^{2}[/tex]+5x+5-7x=7x-7x

If you want combine liked terms:

3[tex]x^{2}[/tex]-7x+5x+5=0

3[tex]x^{2}[/tex]-2x+5=0

Hope this helps!
