Question

What is the value of r in the equation

-1.5(4-r) =-12

Answer 1

r= -5

Explanation:

-1.5(4-r) = -12

-4.5r+1.5r = -12

1.5r= -12+4.5

1.5r= -7.5

r = -5

Answer 2

The Answer is -4

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
