Given
[tex]6(5-3x)-5(3x+2)[/tex]
Distribute
[tex](30 - 18x)+(-15x-10)[/tex]
Rearrange and solve
[tex](-18x+30)+(-15x-10)[/tex]
Subtract (30) to both sides
[tex](-18x+30)-30+(-15x-10)-30\\(-18x)+(-15x-40)[/tex]
Add (15x) to both sides
[tex]+15x(-18x)+(-15x-40)+15x\\-3x+40[/tex]
Your answer is
[tex]-3x+40[/tex]
