Worksheet Overview

QUESTION 1 of 10

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.
