One answer is : 6x+6y + wx+wy = (6+w)x + (6+w)y.
-(v + 5)(w - x)
w - x + x = wand w + x - x = w are true for all values of w and x and that is why they are called identities.
w - x + x = wand w + x - x = w are true for all values of w and x and that is why they are called identities.
They are identities because they are true for ALL values of w and x.
if x + y = w, then x = w - y

you can not solve this equation
Identify the property x + 12 = 12 + X

One answer is : 6x+6y + wx+wy = (6+w)x + (6+w)y.
-(v + 5)(w - x)
The idea is that a regular equation is simply a statement that two quantities are the same; this statement may, or may not, be true - or it may depend on the value of the variables. For example, x + 2 = 5 is true, only if x is replaced with 3. An "identity" is an equation that is true for any value of the variables.
