Chain Reaction – Level 1 – Medium

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!

Your Workings For Chain Reaction

1) Solve: 6x + 6 = 5x + 18

A =

2) Use your answer from Q1 as “a”. Now solve: 4a – x + 7 = 43

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 + 3) – c = -41

D =

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

E =

Chain Reaction – Medium

One move per line: Medium chains are where messy working causes the most problems.

  • Expand brackets carefully (write every term).
  • Collect like terms before rearranging.
  • Only then isolate the variable or extract the required value.

Speed tip: rewrite the next step immediately after substituting (so it becomes a normal standalone equation again).
