x/2 - 5 =3
add 5 to each side. this is the addition property of equality
it says when we add the same thing on both sides of the equation, we are not changing the value of the equation
we are using this to get the variable on one side and the constant on the other
x/2 -5+5 = 3+5
x/2 =8
multiply each side of the equation by 2
we are using the multiplication property of equality
it says when we multiply each side of the equation by the same thing, we are not changing the value of the equation
x/2 *2 = 8*2
x = 16
