I need help.. but we are only doing question 34 please answer quickly

Answer: 33. r=13.6 34. m=12
Step-by-step explanation:
33.
-0.8+r=12.8
-0.8+r+0.8=12.8+0.8
r=13.6
34.
[tex]\displaystyle\\-\frac{m}{3}=-4\\\\\frac{m}{-3}=-4[/tex]
Multiply both parts of the equation by -3:
[tex]\displaystyle\\\frac{m}{-3}(-3)=(-4)(-3)\\\\ \frac{m(-3)}{-3} =12\\\\m=12[/tex]
