Answer:
The answer is option 2.
Step-by-step explanation:
First, you have to eliminate brackets, you have to divide -1.5 to both sides :
[tex] - 1.5(4 - r) = - 12[/tex]
[tex] - 1.5(4 - r) \div - 1.5= - 12 \div - 1.5[/tex]
[tex]4 - r = 8[/tex]
Next you have to solve r :
[tex]4 - r = 8[/tex]
[tex] - r = 8 - 4[/tex]
[tex] - r = 4[/tex]
[tex]r = - 4[/tex]
