Question

Find the values of x and y to make the following numbers equal

Answer 1

`-(2)/(x),(y)/(5),-0.2`

If all numbers has to be equal, that means:

`\begin{gathered} (-2)/(x)=-0.2 \\ (y)/(5)=-0.2 \end{gathered}`

Let's solve the value of x and y that makes the equation above equal. Let's start with x.

`\begin{gathered} (-2)/(x)=-0.2 \\ \text{Cross multiply.} \\ -2=-0.2x \\ \text{Divide -0.2 on both sides.} \\ (-2)/(-0.2)=(-0.2x)/(-0.2) \\ 10=x \end{gathered}`

The value of x is 10.

Let's solve for y.

`\begin{gathered} (y)/(5)=-0.2 \\ \text{Cross multiply.} \\ y=-1 \end{gathered}`

The value of y is -1.
