How do you solve X-2x equals 3x-43x plus 1?
For x-2x= 3x-43x+1 x-2x= -x and 3x-43x+1 = -40x+1 so -x= -40x+1 subtract -x from both sides 0= -39x +1 -1 = -39x so 1=39x so x=1/39

12 is 40 percent of what number?
To find the number that 12 is 40% of, you can set up a proportion. Let x represent the unknown number. The proportion would be: 12/x = 40/100. Cross multiplying gives you: 12 * 100 = 40x. Simplifying further, you get: 1200 = 40x. Dividing both sides by 40 gives you x = 30. Therefore, 12 is 40% of 30.
How do you solve X-2x equals 3x-43x plus 1?
For x-2x= 3x-43x+1 x-2x= -x and 3x-43x+1 = -40x+1 so -x= -40x+1 subtract -x from both sides 0= -39x +1 -1 = -39x so 1=39x so x=1/39
