Question

What coefficient of d makes theexpressions equivalent? -1/3(2.7d+1.8)=(?d-0.6)

Answer 1

hello

the equation given is

`-(1)/(3)(2.7d+1.8)=(xd-0.6)`

let's resolve both sides of the equation

`-(1)/(3)(2.7d+1.8)=-0.9d-0.6`

now let's equate both sides

`\begin{gathered} -0.9-0.6=xd-0.6 \\ \text{comparing both sides} \\ x=-0.9 \end{gathered}`

the missing coeffiecient to make both expression equal is -0.9
