1) Solve: 2x + 3 = 13

A =

2) Use your answer from Q1 as “a”. Now solve: a + x = 12

B =

3) Use your answer from Q2 as “b”. Now expand and simplify: (x + b)(x + 1) – what is the constant term?

C =

4) Use your answer from Q3 as “c”. Now solve: (c + x)/2 = 7

D =

5) Use your answer from Q4 as “d”. Now factorise: x² + (d)x + 12

E =

Chain Reaction – Easy

Two-pass approach:

Pass 1: glance at every step and identify the action (solve / simplify / expand / factorise / “find the coefficient”).
Pass 2: solve step-by-step, substituting each result into the next.

Easy check: once you find a value (a, b, c…), quickly plug it back into that step to confirm it works before you use it later.
