Answer:

-2

Step-by-step explanation:

We are given the following;

  • [tex]\text{Expression:} \ 2x - y[/tex]
  • [tex]y = -4[/tex]
  • [tex]x = -3[/tex]

Plug the value of y and x into the expression;

[tex]\implies 2x - y[/tex]

[tex]\implies 2(-3) - (-4)[/tex]

Simplify the expression as needed;

[tex]\implies 2(-3) - (-4)[/tex]

[tex]\implies -6 + 4[/tex]

[tex]\implies \boxed{-2}[/tex]

Therefore, -2 is the value of 2x - y, when x = -3 and y = -4.
