Further Algebra SummaryBrackets can be used in algebra to keep things together e.g. (x + 5)
We can write expressions like 2(x + 5) meaning that (x + 5) is multiplied by 2, and (x + 5)÷2 or (x + 5)/2 where (x + 5) is divided by 2.
What we do to the bracketed term on one side of the equations must also be done to the other.
Once the bracketed term is no longer multiplied or divided by anything, the brackets are no longer needed: solve as normal! Related Topic: Equations
