(2x+3)/(15)=(9)/(10)\qquad\text{cross multiply}\\\\10(2x+3)=(9)(15)\qquad\text{use distributive property}\\\\(10)(2x)+(10)(3)=135\\\\20x+30=135\qquad\text{subtract 30 from both sides}\\\\20x=105\qquad\text{divide both sides by 20}\\\\x=(105)/(20)\\\\x=5(5)/(20)\\\\x=5(1)/(4)\to x=5.25\\\\Answer:\ \boxed{x=5(1)/(4)=5.25}

remember that when you bring ÷ to the other side of the equal sign it'll become multiply instead
