Chain Reaction – Level 1 – Easy

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: 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 =
