Question

-3(3x+15)-(10+x)=35 help

Answer 1

Explanation :

To solve for x, we first expand the expressions on the left-hand side of the equation:

`-3\mleft(3x+15\mright)-\mleft(10+x\mright)=35`

Expanding the expressions gives

`-3\mleft(3x+15\mright)=-9x-45`

and

`-(10+x)=-10-x`

Therefore, the original expression becomes

`-9x-45-10-x=35`

Now we simplify the lefthand side to get

`(-9x-x)+(-45-10)=35`
`-10x-55=35`

Adding 55 to both sides gives

`\begin{gathered} -10x=90 \\ \therefore x=-9 \end{gathered}`

Hence, the solution is x = -9.
