They are not equal.
Expression
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations that are formed according to rules which is dependent on the context.
Given equations
1/4(8y -12)
2y - 12
To find
1/4(8y -12) equivalent to [tex]\dfrac{1}{4}(8y-12)\neq (2y - 12)[/tex]
Solution
[tex]\dfrac{1}{4}(8y-12)\\[/tex]
multiplying [tex]\dfrac{1}{4}[/tex] inside the brackets,
[tex]=(\dfrac{1}{4}\times 8y)-(\dfrac{1}{4}\times 12)\\[/tex]
[tex]=(2y)-(3)\\[/tex]
[tex]=2y-3[/tex]
Therefore, [tex]\dfrac{1}{4}(8y-12)\neq (2y-12)[/tex]
Hence, they are not equal.
