Chain Reaction – Level 1 – Medium

Topics: answers, chain, multi-step reasoning, questions

Each answer you find is used inside the next question. Work through the full chain carefully – if you get one wrong, it affects the rest!

1) Solve: 8x + 10 = 3x + 40

A =

2) Use your answer from Q1 as “a”. Now solve: 4a – x + -2 = 14

B =

3) Use your answer from Q2 as “b”. Now simplify: (x + 5)(x + b) – what is the coefficient of x?

C =

4) Use your answer from Q3 as “c”. Now solve: 2(x + 4) – c = 25

D =

5) Use your answer from Q4 as “d”. Now factorise: x² – dx + 36

E =

Carry your labels consistently: if Step 2 says “use your answer from Q1 as a”, make sure you keep using that exact label.

Tip: if you ever end up with awkward numbers, pause and re-check the previous step — Medium chains often stay fairly neat.
