Evaluate (4x+y)^2-3z for x=2,y=-1,and z=5

34

Step-by-step explanation:

(4x+y)^2-3z for x=2,y=-1,and z=5

LET'S SUBSTITUTE.

(4(2)+(-1))^2-3(5)

TAKE NOTE OF THE SIGNS (-) (+).

=(8-1)^2 - 15

= (7)^2 - 15

SOLVE THE NUMBERS ASSOCIATED WITH THE BRACKETS FIRST.

= 49 - 15

= 34

hi there! my name is zalgo and i am here to you out today. the answer is pretty simple (in a way). this equation equals to 25.2!

i hope this answer !

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
