The number representing Liam's share is 2; for Sarah's share, it is 3. The difference of those is 1, so each 1 unit of share must be £30, the difference between the amount Sarah got and the amount Liam got.
Emily got 5 shares or £30 × 5 = £150.
If you would like to solve the equation x^2 + 9x - 22 = 0, you can do this using the following steps:
<span>x^2 + 9x - 22 = 0
</span>(x - 2) * (x + 11) = 0
1. x = 2
2. x = - 11
The correct result would be x = 2 and x = - 11.
