Answer:
r= -5
Step-by-step explanation:
-1.5(4-r) = -12
-4.5r+1.5r = -12
1.5r= -12+4.5
1.5r= -7.5
r = -5
Answer:
The Answer is -4
Step-by-step explanation:
Substitute x for -4: -1.5(4-[-4]) = -12
Four minus negative four the same as four plus four: -1.5(4+4)=-12
Four plus four is eight: -1.5(8)=-12
Negative 1.5 multiplied by eight is negative twelve: -12 = -12
