Answer:
4+x
Step-by-step explanation:
4 and however much juice he had before. there is not enough information to answer this question with certainty.
They are a not equal because one variable is positive and the other is not
Solve for X in the 2nd equation:
x+2z = 0
Subtract 2z from both sides:
x = -2z
Replace x in the first equation with -2z
-2z +y -z = 1
Combine like terms:
-3z +y = 1
Add 3z to both sides:
y = 3z +1
Replace x and y in the 3rd equation:
2(-2z) + 2(3z+1) = 4
-4z + 6z + 2 = 4
2z +2 = 4
2z = 2
z = 1
Now replace z with 1 in the other equations for x and y:
x = -2z = -2(1) = -2
y = 3z +1 = 3(1) +1 = 3+1 = 4
So you have x = -2, y = 4 ans z = 1
The answer would be written as (-2,4,1)
You can say 1 and 7/11 is 18/11 and 2 and 1/2 is 5/2 so :
18/11 ÷ 5/2 so 18/11 * 2/5 = 36/55 = 0.654 :)))
i hope this is helpful
have a nice day
Answer: Sup. it's 16
Step-by-step explanation: Hope dis helps
if x = 2 and our equation is 10 +3(12 ÷ 3x), then u use substitution
So, the equation would become 10 + 3(12 ÷ 3(2)), which is 10 + 3(12 ÷ 6)
12÷6= 2, so the equation becomes 10 + 3(2).
3(2) = 6, so the equation would be 10 + 6 = 16
