Q. Identify the properties used.2y=y=44. 4n−2=104n=n=
Apply Transitive Property: First, let's look at the expression 2y=y=4. This uses the Transitive Property of Equality, which states if a=b and b=c, then a=c. So if 2y=4 and y=4, then 2y=y.
Solve for y: Now let's solve for y. If 2y=4, then y=4/2, which means y=2.
Isolate n term: Next, we have (n)/(4)−2=10. To solve for n, first add 2 to both sides to isolate the term with n. So, (n)/(4)−2+2=10+2, which gives us (n)/(4)=12.
Multiply to solve for n: Now, multiply both sides by 4 to solve for n. So, 4n×4=12×4, which means n=48.
