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

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted
