Answer:

[tex]65[/tex]

Step-by-step explanation:

Given the following question:

[tex]5a-9(b-c)[/tex]
a = 4
b = 2
c = 7

In order to find the answer, we need to substitute the variables with the numbers given, and then solve using PEMDAS.

[tex]5\times4-9\times(2-7)[/tex]
[tex]2-7=-5[/tex]
[tex]5\times4-9\times-5[/tex]
[tex]5\times4=20[/tex]
[tex]20-9\times-5[/tex]
[tex]9\times-5=-45[/tex]
[tex]20--45[/tex]
[tex]20+45=65[/tex]
[tex]=65[/tex]
