Im not giving ya'll the straight answer because I use it all the time in almost all of my math.

Because you have the value of the variables, all you need to do is plug those variables in and the solve like you usually would (PEMDAS)

Hope this helps and ya'll got this! ;)

Answer 2

Do everything inside of the parenthesis first and then work your way through the problem.

2[(5/2)((7)-5(1/5))]
2[5/2(7-5)]
2[5/2(2)]
2[5]
10

Final answer: 10
