About this worksheet
In class: Build algebra from arithmetic: use a variable to stand for an unknown, write the situation as an expression or equation, then keep both sides balanced when solving and check by substituting the answer back in.
This Grade 7 algebra set is free to print or save as a PDF, and its answer key is computed in code, so it is never wrong.
