  • 1/2x+8=22 8-8=0 22-8= 14
  • 1/2x+8=22 First you need to subtract 8 from each side.
  • This is the inverse step and the equality step. It's inverse because the opposite of adding 8, is subtracting 8. This is also the equality property because to keep the equation equal, you need to subtract 8 from both sides.
  • This is the simplify step because you are narrowing down your equation to see what you have left to solve
  • Now your equation is 1/2x=14
  • 1/2x=14 Now, you need to divide each side by 1/2, so you can isolate the variable
  • 1/2x= 14 1/2 * 2/1 = 1 14/1 * 2/1= 28
  • That step was called the multiplicative inverse operation because you had to get x by itself. Your fraction was 1/2, so you multiplied it by its reciprocal. (basically just dividing)
  • To be fair you divided each side by 2/1. That step is called the equality property of division
  • Our equation is now: x=28 We have found the value of x! This step is called our solution!
