What's the opposite of division? Multiplication

So we multiply 2 on both sides to get A=-10

Hope this helped

[tex]\mathsf{We\ can\ treat\ the\ value\ of\ A\ as\ invisible\ 1\ until\ we\ find\ the\ actual\ value\ of\ it}[/tex]

[tex]\mathsf{\dfrac{1}{2}a=-5}[/tex]

[tex]\mathsf{Multiply\ by\ 2\ on\ both\ of\ your\ sides}[/tex]

[tex]\mathsf{\dfrac{1}{2}a\times2=-5\times2}[/tex]

[tex]\text{Cancel out }\mathsf{\dfrac{1}{2}a\times2}\text{ because it gives you the value of 1}[/tex]

[tex]\text{Keep: }\mathsf{-5\times2}\text{ because it gives the value of a}[/tex]

[tex]\mathsf{-5\times2=-10}[/tex]

[tex]\boxed{\boxed{\mathsf{Answer: a=-10}}}[/tex]
