If you would like to know 55 percent of what number is 495, you can calculate this using the following steps:
55% of what number = 495
55% * x = 495
55/100 * x = 495
x = 495 * 100/55
x = 900
The number you are looking for is 900.
Sample Equation: 3x - 3 = 27
Multiple step:
3x - 3 = 27
<u> + 3 +3</u> Step1. Remove the -3 by adding 3 to both sides
3x = 30
<u>÷3 ÷ 3</u> Step2. Remove the multiplicand 3 by dividing both sides by 3
x = 10
To check: substitute x by its value
3x - 3 = 27
3(10) - 3 = 27
30 - 3 = 27
27 = 27
Attached the solution and work.
