12+11x=17x11x+12=17x
(both sides of the equation)
11x+12−17x=17x−17x
(Subtract 17x from both sides)
−6x+12=0−6x+12−12=0−12
(Subtract 12 from both sides)
−6x=−12−6x−6=−12−6
(Divide both sides by -6)
x=2

x=2
(Works in original equation)
just divide 20 by coefficient of x
x < 20/2
x < 10
37 because you add 13+10=23 7+7=14 and 23+14=37
