Answer:
An equivalent expression to the given expression is;
[tex]6-m=114[/tex]
Explanation:
Given the equation;
[tex]-\frac{1}{2}m+3=57[/tex]
we want to write an equavalent expression to the above;
let us multiply through by 2;
[tex]\begin{gathered} -\frac{1}{2}m+3=57 \\ -\frac{1}{2}m(2)+3(2)=57(2) \\ -m+6=114 \\ 6-m=114 \end{gathered}[/tex]
Therefore, an equivalent expression to the given expression is;
[tex]6-m=114[/tex]
