5(-12x+3)+6(10x+7)=9-x+3x+10​

Answer: x = 19

Step-by-step explanation:

5(-12x+3) + 6(10x + 7) = 9 - x + 3x + 10     Distribute on the left side

-60x + 15 + 60x + 42 = 9 + 2x + 10   combine like terms on the left side

   57 = 9 + 2x + 10        Now combine like terms on the right side

57 = 2x + 19        Subtract 19 from both sides

-19           -19

 38 = 2x       Divide both sides by 2

x = 19
