Substitution With Distributing Negatives

Work through the three drill sheets in order. Use Solve Systems by Any Method, Choose and Explain once elimination is also taught, and the maze as review.

Solve eight substitution systems where a negative must be distributed, as in x = 2y + 7. The directions on the page read: Substitute, distribute the negative, and solve. Write the solution as a pair. An answer key is included.

Yes, both. We made it for 8th grade systems of equations, and it works the same at home or at school. At home, a student can work through it alone and then go over it with you, which shows quickly what is solid and what needs another look. In class it works as independent practice, homework or a warm-up, and you can print one copy or a full set.

Get x or y alone in one equation. Substitute that expression into the other equation and solve it. Then put the value back in to find the other variable and write the pair.

Forgetting to distribute a negative sign when the expression goes into parentheses. Substitution With Distributing Negatives gives eight systems built to practice this step.

Students start at cell 1, solve the system there and follow the arrow next to their answer. A wrong answer leads off the path, so the maze checks the work as students go.
