Answer:

[tex]\huge\boxed{\bf\:19}[/tex]

Step-by-step explanation:

Given,

  • x = 5
  • y = 7

Now, the expression is: [tex]20 - (3y - 4x)[/tex].

To solve this question we just need to substitute the values of x & y in the given expression. Then,

[tex]20 - (3y - 4x)\\= 20 - (3(7) - 4(5))\\= 20 - (21 - 20)\\= 20 - 1\\= \boxed{\bf\:19}[/tex]
