- [tex]\frac{1}{3}[/tex] x
To make the 2 expressions equivalent we require the coefficients of x to be equal.
[tex]\frac{1}{2}[/tex] = [tex]\frac{3}{6}[/tex]
subtracting [tex]\frac{2}{6}[/tex] from [tex]\frac{5}{6}[/tex] = [tex]\frac{3}{6}[/tex]
thus [tex]\frac{5}{6}[/tex] x -[tex]\frac{2}{6}[/tex] x - 4
makes the 2 expressions equivalent
