Question

What is the value of d?



−5.5(d−2)=−12.1

Answer 1

answer:  $d = 4.2$

explanation:

$-5.5(d-2)=-12.1$  | distribute the -5.5 into the parentheses

$-5.5d + 11 = -12.1$  | subtract 11 and move it over to -12.1

$-5.5d = -23.1$  | divide by -5.5

$d = 4.2$  | final answer

Answer 2

-5.5(d - 2) = -12.1

-5.5d + 11.0 = -12.1    distributed -5.5 on the left side

           -11.0    -11.0

-5.5d           = -23.1

             $\frac{-5.5d}{-5.5} = \frac{-23.1}{-5.5}$

               d = 4.2

Answer: d = 4.2
