How would I simplify this equation, where do I start?
How would you simplify this:(x + 3y - 5z) - (x - 2y + 6z)I need assistance on solving
It appears that all they want you to do is to distribute the negative sign through the second parentheses and combine like terms. It would turn into:
x + 3y - 5Z - x + 2y - 6Z
Combine all the x's, all the y's and all the z's, and write the expression:
5Y - 11Z
Isn't that cool the way that the opposite signs on the x's make them disappear?
This is not an equation - there's no equal sign, right? We can't actually solve to get values for the variables. Is that what was confusing you?
By the order of operations, multiplication comes before addition. The (x-2y+6z) is being mulitplied by -1, so distribute that through first. Then remember that addition is commutative and you can add/subtract like terms together, for example 3y + 4y = 7y.
