Question

Solve for X in the equation

Answer 1

We are given the following equation

`-(3)/(2)=(x)/(10)`

Let us solve the equation for x

Firstly, apply the cross multiplication

`\begin{gathered} -(3)/(2)=(x)/(10) \\ -3\cdot10=2\cdot x \\ -30=2x \end{gathered}`

Now, divide both sides of the equation by 2 (so that the 2 on the right side gets canceled)

`\begin{gathered} -30=2x \\ (-30)/(2)=(2x)/(2) \\ -(30)/(2)=x \\ -15=x \\ x=-15 \end{gathered}`

Therefore, the value of x is -15
