What is x in 3x-9 EQUALS 27? X= 36 THIS IS THE WORK: 27 + 9= 36 36/3= 12 :)
3x+12=x+48: 3x-x=-12+48 2x=36 x=18
3a + 9 =3X(a + 3)
3x - 6 = -3x + 36Add 3x to each side:6x - 6 = 36Add 6 to each side:6x = 42Divide each side by 6:x = 7
Given that 3x = 54,divide each side by 3,then 3x/3 = 54/3,and after simplifying the fractions, x = 18.
