Answer:
Step-by-step explanation:
move all the terms to the right so your equation will equal 0. then look for the common denominator. which in this case is 60 (5*4*3).
multiply all terms by 60 then simplify.
12(2x-3)-15(6-3x)+120-20(7x)=0
24x-36-90+45x+120-140x=0
combine like terms and then divide
-71x=6
x=-6/71
(do not forget parenthesis when simplifying they are very important when it comes to distributing the minus sign)
