Evaluate 3x+y
If x = -4 and y = 2

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

the answer is d

step-by-step explanation:

y+3=-4(x-2)

y+3=-4x+8

  -3         -3  

y=-4x+5
