If you have an equation such as x-y = v+w this is the same as v+w = x-y Whatever operation you perform on one side of the equals, you must perform on the other side.

for example, v+w+2 = x-y+2

​also, you can simplify expressions using brackets

2(a+2) = 2a+4 This equation works for every value of a.

This is the foundation for constructing and solving equations.
