So we need to solve:

First is important to note that both terms on the left side of the equation have a common factor because they are both divided by y. Then:

Then:

So the solution is y=6. Then option A is correct and you need to write the 6 between the symbols { }.
Answer:
x=4
Step-by-step explanation:
Problem set up is: 5x-6=14
5x=20
x=4
Answer:
x = 8
Step-by-step explanation:
10x - 2 (x + 6) = 52
Let X become 8
10 (8) - 2 (8 + 6) = 52
80 - 2 (14) = 52
80 - 28 = 52
52=52
