To solve the equation: 1. X + 9 / 2 equals 12 2.0.45x equals 8.13 4 / 4 equals 3 / 8

To solve the equation: 1. X + 9 / 2 equals 12 2.0.45x equals 8.13 4 / 4 equals 3 / 8


1. If it's 9 / (x + 2) = 12, that's it
x=9/12-2
x=-15/12=-1.25
If x + 9 / 2 = 12, x = 12-9 / 2 = 12-4.5 = 7.5
2、x=8.1/0.45=18
3、x=3/8*4
x=3/2=1.5



When the ratio of 1 / 4 to 1 / 3 equals x to 12, the first step of 1 / 3 x equals 1 / 4 times 12 is based on


1/4/(1/3)=3/4
x/12=3/4
x=9
