'Does it Fit?' worksheet

Key stage:  KS 3

Curriculum topic:   Algebra

Curriculum subtopic:   Use Standard Mathematical Formulae

Difficulty level:  

Worksheet Overview

Given the formula a = 2b + 3, we can test to see whether the solution a = 10, b = 4 works.


We substitute b = 4 into the formula to see whether it gives a = 10.


a = 2b + 3

a = 2 x b + 3

a = 2 x 4 + 3

a = 8 + 3

a = 11


So a = 10, b = 4 does not fit.
