What is the value of r in the equation

-1.5 (4-r) = -12

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

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
