Question

Haii I need Help please.! <3 /.\
Evaluate the following expression using the values given:
Find 4x - y - 2z if x = -2, y = 3, and z = -2
Thank You <3

Answer 1

the answer is -7

Answer 2

4(-2)-3-2(-2)=-7

Answer 3

Thank You Dear.!! <3

Answer 4

4x - y - 2z

4(-2) - y - 2z ... replace x with -2 (since x = -2)

4(-2) - 3 - 2z ... replace y with 3 (since y = 3)

4(-2) - 3 - 2(-2) ... replace z with -2 (since z = -2)

Now evaluate and simplify

4(-2) - 3 - 2(-2)

-8 - 3 + 4

-11 + 4

-7


This means 4x - y - 2z = -7 when x = -2, y = 3, and z = -2

Answer 5

Can i ask another real quick.?

Answer 6

i got that by putting it into my calaculator

Answer 7

x over 8 - 5 = -1?

Answer 8

x=32

Answer 9

x/8=5-1, 8*5=32

Answer 10

well you would go head and do 8-5 to get x/3=-1 then multiply by 3 on each side to get x=-3
