What is the value of r in the equation

-1.5(4-r) =-12

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

X = 6

y= 7

this is the correct answer
