Answer:

[tex]257[/tex]

Step-by-step explanation:

We want to evaluate:

[tex]5(41 - x) + ( - 7(y + x)[/tex]

for x=-2 and y=-4.

We substitute to get:

[tex]5(41 - - 2) + ( - 7( - 4 + - 2)[/tex]

We now simplify to get:

[tex]5(41 + 2) - 7( - 6)[/tex]

[tex]5 \times 43 + 42[/tex]

[tex]215 + 42 = 257[/tex]
