Answer 1

Answer:

Step-by-step explanation:

3x+y

first start by putting each into the equation

3 ( x=-4)+(y+2)

x(-4)+2

use order of operations (PEMDAS)

multiplication is first, so you do x*-4

you get -4x

then add 2 to that

since x in an unown answer, you cannot add 2 +4

so the answer si -4x+2

Answer 2

-10

Step-by-step explanation:

3x + y

= 3(-4) + 2

= -12 + 2

= -10
