Question

35 = 3d + 6dmy teacher didn't explain this very well and I'm confused

Answer 1

`d=(35)/(9)`

Step-by-step explanation

we have a equation with 1 unknow value( d), so to find this we need to isolate d

`35=3d+6d`

Step 1

add like terms

`\begin{gathered} 35=3d+6d \\ 35=9d \end{gathered}`

Step 2

Division property of equality states that when we divide both sides of an equation by the same non-zero number, the two sides remain equal,

hence , divide both sides by 9

`\begin{gathered} 35=9d \\ (35)/(9)=(9d)/(9) \\ (35)/(9)=d \end{gathered}`

therefore, the value for d is

`d=(35)/(9)`

I hope this helps you
