Y = 2x + 5 that is my answer
X + y = 33
x - y = 9 Add the 2 equations together
---------------
2x = 42 Divide both sides by 2
x = 21
Use the original equation and plug 21 in for x, then solve.
x + y = 33
21 + y = 33
Subtract 21 from both sides
y = 12
One list had 21 items on it and the other list had 12 items on it.
Isolate z by itself:
To simplify variables with powers, subtract the smaller power from the bigger power:
The exponent will be
-3.
Answer:
y=40
x=59
z=81
Step-by-step explanation:
therfore..40+59+81=180
The product is the answer to a multiplication problem.
