Question

Solve for x. 1. 5(x-10)=4002.10(10+x)=50

Answer 1

1. x=90

2. x=-5

Step-by-step explanation:

Part 1

Given the equation

`5(x-10)=400`

First, we divide both sides of the equation by 5.

`\begin{gathered} (5(x-10))/(5)=(400)/(5) \\ x-10=80 \end{gathered}`

Next, we add 10 to both sides.

`\begin{gathered} x-10+10=80+10 \\ x=90 \end{gathered}`

Part 2

Given the equation

`10(10+x)=50`

First, we divide both sides of the equation by 10.

`\begin{gathered} (10(10+x))/(10)=(50)/(10) \\ 10+x=5 \end{gathered}`

Next, we subtract 10 from both sides.

`\begin{gathered} 10-10+x=5-10 \\ x=-5 \end{gathered}`
