1) You will need to simplify both sides of the inequality.
$6x-13 \ \textless \ 6x-12
$

2) Now you will need to subtract the like terms which leaves you with

At sunrise, the temperature was –4.5°C. During the day, the temperature rose 9.7°C and then fell 4.8°C.

ollegr [7]

-4.5 rose 9.7 then fell 4.8

-4.5 + 9.7 = 5.2

5.2 - 4.8 = 0.4
